Illinois car wash owners are hearing two stories at once. National platforms still want density. At the same time, the easy-multiple era is ending. Scale buyers are still writing checks. They are also restructuring, selling portfolios, and asking harder questions about memberships, rent, and replacement capital.
That mix matters if you own one tunnel in the collar counties or three sites downstate. Consolidators are still buying. Timing and evidence matter more than they did when almost any express wash drew a crowded process. Pair this playbook with our guide to selling a car wash business and a confidential sell-a-business process if you are weighing outreach.

What the 2025 wash roll-up actually showed
On April 10, 2025, Driven Brands completed the sale of its U.S. car wash business to Express Wash Operations, LLC, doing business as Whistle Express Car Wash. The Driven Brands Form 8-K on the U.S. car wash sale states aggregate consideration of $385 million. That figure included about $255 million in cash and a $130 million interest-bearing seller note. Final proceeds were subject to customary adjustments and fees.
The buyer, which is backed by funds managed by Oaktree Capital Management, publicly described a combined network of about 530 express locations across 23 states after closing. That is a scale platform, not a Main Street listing. It is also a reminder that even large portfolios trade with mixed consideration. A headline price that includes a seller note is not the same as cash at close.
The same cycle produced stress, not only trophies. ZIPS Car Wash filed Chapter 11 in the U.S. Bankruptcy Court for the Northern District of Texas in February 2025. It later emerged after a lender-backed reorganization. Separate news reports in early 2025 said the owners of Spotless Brands were exploring a sale. Those reports were not a closed deal, and any valuation figure in them was unconfirmed. Treat rumors as rumors. Treat court filings and SEC reports as facts.
The lesson for an Illinois owner is not “get out now.” It is that platforms still need sites, but underwriting is more disciplined. Buyers who overpaid on leverage are not a template for your asking price.
Why Illinois density still draws buyers
Car washes sit in Census NAICS 811192. The Census Bureau NAICS definitions cover establishments that clean, wash, or wax vehicles, including self-serve and automatic formats. That code mixes express tunnels, in-bay automatics, detail shops, and mobile units. A buyer comparing you to a national express chain is not comparing like with like unless the operating model matches.
Chicagoland and the collar counties still offer traffic, rooftops, and membership density that regional platforms want. Naperville, Aurora, Schaumburg, and the northwest suburbs often see more inbound interest than a single-site wash in a smaller downstate city. That does not make a downstate wash unsellable. It changes the buyer mix. You may see more owner-operators and regional groups, and fewer national roll-ups hunting a fill-in site.
Density is not a slogan. Buyers map competing tunnels, membership overlap, and cannibalization. A strong wash next to a new platform site can lose members without a single operational mistake. Bring a simple competitive map to the first serious meeting. Hide the store name until an NDA is in place.
Disciplined underwriting: memberships, not folklore
Most owner-operated Illinois washes still price off Seller’s Discretionary Earnings, or SDE. SDE is the economic benefit a full-time working owner can take after a clean recast. Larger, manager-run platforms often use adjusted EBITDA instead. EBITDA is earnings before interest, taxes, depreciation, and amortization after you restore a market manager wage. See our explainer on what seller’s discretionary earnings means before you quote a multiple you heard at a trade show.
Platform buyers now test the membership file, not only last year’s profit. They want active unlimited counts, churn, average ticket, retail versus membership mix, and whether the POS export ties to bank deposits. A wash that looks busy on Saturday can still have a weak recurring base. Recurring revenue supports a higher multiple only if it transfers and if churn is documented.
Add-backs still matter, and they still get cut. An add-back is an adjustment that moves reported profit toward the cash a buyer can keep. Personal vehicles, one-time equipment repairs, and family wages can be real. Deferred maintenance, unpaid family labor, and below-market rent are not free upgrades. They are costs a buyer will restore. Inflating SDE is how you get a high teaser and a retrade in week six of diligence.
Rule-of-thumb multiples are folklore until they sit on a recast. Our 2026 Illinois acquisition multiples discussion is context, not a quote for your tunnel. A hypothetical 4.5x on undocumented SDE is not a market. It is a caption.
Single-site versus multi-site: different clocks
A one-site owner often sells to an operator who will stand in the kiosk and greet members. That buyer may use an SBA 7(a) loan. The SBA guidance on merging or acquiring a business treats valuation as one step beside diligence, agreements, and professional help. SBA underwriting wants clean books, a financeable lease or owned real estate, and a story that survives tax returns.
A two- or three-site owner can attract a platform that already has a district manager in Illinois. That buyer may pay more for density and a transferable crew. That buyer will also discount owner-dependent hours, short ground leases, and equipment that is near replacement. Scale does not erase diligence. It often deepens it.
If you own the land, decide early whether dirt travels with the wash. Many deals split the going concern from the real estate. Mixing them into one “what I need to retire” number hides two risks. Operating cash flow depends on members and labor. Property cash flow depends on rent, pavement, and the roof. Price them on purpose, then combine only if both sides of the table agree.
Illinois closing steps platforms will not skip
A wash sale in Illinois is still a business sale. It still has Illinois layers. The purchaser in a bulk transfer of business assets generally must file Form CBS-1 with the Illinois Department of Revenue. The Illinois Department of Revenue bulk sales notice (Form CBS-1) is due at least ten business days before the transfer. If the notice is late, the buyer can be personally liable for the seller’s unpaid Illinois tax up to the value of the property acquired. Read our Illinois Bulk Sales Act compliance overview and put the notice on the closing calendar at letter of intent, not the week of funding.
Keep the selling entity in good standing with the Illinois Secretary of State business services office. Lapsed annual reports create last-minute scrambles that make buyers nervous. Municipal discharge, water, and sewer permits rarely “travel” on a handshake. Confirm with the city or village what a change of ownership requires.
Lease assignment is a frequent killer on pad sites and ground leases. Landlord consent, remaining term, and personal guarantee release can take months. See our guide to commercial lease assignment when selling an Illinois business. A platform will not fund a tunnel with two years left and no options. An SBA lender will not either.
Environmental and water systems belong in the data room. Reclaim equipment, discharge permits, and any notices from local authorities should be disclosed early. Hiding a problem does not raise the multiple. It delays closing or ends the deal.
How to time outreach without leaking the tunnel
Timing is not a calendar app guess. It is a readiness test. If memberships are stable, books recast, and the lease is financeable, you can run a confidential process while platforms are still filling maps. If churn is rising, a competitor just opened, or the conveyor is due for a six-figure rebuild, fix the file first. Selling into a known decline is how you meet “disciplined underwriting” the hard way.
Confidentiality is a process. Use a blind teaser, an NDA, and staged release of the confidential information memorandum, or CIM. A CIM is the underwriting narrative, not a brochure. Do not post identifiable photos of your tunnel on a public marketplace if employees and competitors would recognize the site. For the broader sequence, see when is the right time to sell and business valuation planning.
Unsolicited calls from “we buy car washes” shops are not a market. They are a single conversation. You can listen. Do not grant long exclusivity before you know what other qualified buyers would pay. A letter of intent, or LOI, typically sets price, structure, deposit, exclusivity, and diligence. Read it as a proceeds and risk document, not as a compliment.
Hypothetical: two owners, two clocks
These figures are hypothetical teaching tools. They are not quotes, comps, or promises.
Owner A runs one express tunnel in a DuPage County suburb. Normalized SDE is $410,000 after restoring a manager wage the buyer will need. Memberships are 2,100 unlimited plans with documented monthly churn under 4 percent. The ground lease has 18 years remaining with options. A recast that a lender can rebuild might support a planning range in the mid-single-digit SDE multiples, before rent, working capital, and equipment reserves. If Owner A waits two years while a new platform tunnel opens a mile away, the same recast can support a lower range even if the owner “feels busy.”
Owner B holds three sites in a mid-size downstate market. Combined adjusted EBITDA after a district manager is $620,000. One site needs a dryer replacement within 12 months. The other two are clean. A platform may pay for density and still subtract the capex. An owner-operator may finance one site and not three. Owner B’s clock is about packaging a portfolio that a buyer can underwrite, not about chasing the last national headline multiple from 2021.
Neither owner should set price from a neighbor’s rumor. Both should decide whether they are selling now because the file is strong, or waiting because the file is not.
What to prepare before anyone tours the site
Build a data room before you need it:
- Three years of business tax returns and matching monthly P&Ls
- POS membership exports that tie to deposits
- Equipment list with age, service logs, and known replacements
- Lease, amendments, and landlord contact for an estoppel
- Water, sewer, and discharge permits
- Payroll roster by role, without names on the teaser
- A one-page competitive map with distances, not brand gossip
That package is how you meet a more disciplined buyer without improvising. It is also how you keep employees from learning the sale from a stranger in the vacuum bay.
Frequently Asked Questions
Are consolidators still buying Illinois car washes in 2026?
Yes, platforms still need density in many maps. They are more selective about membership quality, lease term, and capital spending. A prepared owner can still run a process. An unprepared owner should not expect 2021 terms.
Does the Whistle Express deal set my multiple?
No. That transaction was a large portfolio sale with cash and a seller note. Your wash is a different size, risk, and capital stack. Use the deal as proof that scale buyers still transact, not as your asking price.
Should I wait until the next roll-up wave?
Waiting can help if you need time to recast, extend a lease, or replace equipment. Waiting while churn rises or a competitor opens rarely helps. Time the file, not the headlines.
Will an SBA buyer pay as much as a platform?
Not always. Some SBA buyers close with strong terms and fewer integration risks. Some platforms pay for density and still retrade on diligence. Compare cash at close, notes, and certainty, not only the headline.
What Illinois filings delay a wash closing?
Bulk sales notice, Secretary of State good standing, municipal permits, and lease consent are the usual delays. Start them at LOI. Do not treat them as closing-week paperwork.
How do I keep the sale confidential?
Use a blind teaser, NDA, buyer screening, and staged CIM access. Limit site tours. Brief key staff only when counsel agrees the timing is right.
