Auto repair shops in Illinois sell for 2x to 3.5x SDE on average. A shop generating $200,000 in SDE might sell for $400,000–$700,000 depending on equipment condition, lease security, staff quality, and whether the business is dependent on a particular technician or owner-mechanic.
Equipment and Real Estate
Lift count, alignment equipment, diagnostic tools, and air compressor systems are all included in valuations. Shops that own their real estate often have a higher total transaction value — and buyers frequently want the real estate sold separately or leased back at favorable terms.
Franchise vs. Independent
National franchise auto repair locations (Midas, Meineke, AAMCO) sell differently from independents. Franchises provide brand recognition and marketing support but require franchise approval of the buyer. Independent shops with strong Google reviews and long-standing customer relationships can command similar multiples without the franchise fee overhead.
SBA financing is widely available for auto repair shops, making them accessible to a broad range of buyers. A well-documented shop with 3 years of clean tax returns is in strong shape to attract qualified, financed buyers.

How Illinois buyers put a number on how to value an auto repair shop
This page is the valuation guide. It is not the sale-process playbook. Seller’s discretionary earnings (SDE) is the cash a full-time working owner can take after you normalize the books. Start with the tax return. Add owner pay and one-time costs. Subtract the wage you must pay to replace the owner.
Independent repair recasts around bay throughput and parts margin, not a one-time wholesale-fleet job. Add back owner-technician W-2, then subtract a market-rate tech if the seller still turns wrenches 40 hours. Warranty and sublet spikes come out. A 2x–3.5x SDE band assumes the bays stay full without the seller’s personal following walking out.
Planning band on this vertical: 2x–3.5x SDE. That is a range, not a quote. BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across all reported closed deals. Do not use that marketplace average as this shop’s appraisal.
A worked planning example (illustration)
Illustration only — not a quote for any Illinois shop. A auto repair shop whose tax return shows $67,000 of net profit is not worth $67,000 × a rumor multiple.
Add back the owner’s $55,000 W-2 and payroll tax, $27,500 of discretionary benefits, $6,500 of accepted one-time cost, and $6,500 of personal expenses that a buyer will not run. Then subtract $17,000 of replacement labor if the owner still diagnoses, sells, or closes the books.
Adjusted SDE in this illustration is $145,000. At 2.75x, enterprise value is $398,750 before debt, working capital, holdback, and tax.
SDE line items buyers actually use
- Reported net profit (tax return, not the marketing P&L)
- + Interest expense
- + Income taxes (not payroll, sales, or property tax)
- + Depreciation and amortization
- + Owner W-2, bonuses, and payroll taxes on the owner
- + Discretionary owner benefits that a buyer will not keep (auto, personal travel, family on payroll with no role)
- + Accepted one-time or non-recurring expenses
- − Market-rate replacement labor for owner work that will not transfer
- = Seller’s Discretionary Earnings (SDE)
What moves the multiple up or down
- Technician bench that survives the seller leaving the pit
- Fleet accounts on paper, not a handshake
- Lift and scan-tool age
- Lease term versus a landlord who wants the bays for storage
- Customer-pay mix versus warranty or sublet dependency
What does not transfer with the price
Illinois does not issue a statewide mechanic license. ASE is voluntary. The shop needs a municipal business license, EPA discipline for waste oil, filters, and refrigerant, and Secretary of State paperwork if it issues temp tags or does emissions-adjacent work. Those accounts and the EPA generator status do not silently follow the stock sale.
Diligence that changes the number
- Bay count, lift age, and alignment or scan-tool capability
- ASE or OEM training on the remaining technicians — not the seller
- Customer-pay vs fleet vs warranty mix and parts-return rates
- Lease, environmental waste contracts, and used-oil storage
- Mitchell / AllData / shop-management software ownership
- Repeat-customer rate and whether the book is seller-named
When you want the close calendar instead of the math, read how to sell. This page stays on value.
Documents to gather this week
- Three years of signed business tax returns and matching P&Ls
- Year-to-date P&L, balance sheet, and three months of bank statements
- Current lease, amendments, and a plain-English remaining term
- License and permit list, including who holds each card
- Top-customer concentration (names redacted until an NDA)
A simple Illinois close calendar
Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.

Start with the 2x–3.5x band on this vertical, after you adjust seller’s discretionary earnings. Marketplace-wide 2.7× cash flow from BizBuySell Q2 2026 is not your quote.
Illinois does not issue a statewide mechanic license.
Most prepared Main Street sales take about six to twelve months from cleanup to close. License transfers, landlord consent, and SBA underwriting add weeks.
CBS-1 is the Illinois bulk-sale notice. File it at least ten business days before an asset transfer that meets the statute. Late filing can put Illinois tax risk on the buyer.
