Selling an auto repair shop or car wash

Repair demand starts with the cars on the road. S&P Global Mobility counted 289 million vehicles in operation in its May 2025 analysis, with a large group of 2015 to 2019 models coming off warranty¹. Driven Brands, the owner of Take 5 Oil Change and Meineke, notes that cars older than three to five years may be out of factory warranty and tend to need more maintenance⁴.

Labor is the other half. The Bureau of Labor Statistics counted about 825,800 automotive service technicians and mechanics in 2025 and projects about 66,200 openings a year through 2035, mostly to replace people leaving the trade². A shop with a stable, trained bench solves a problem every buyer has. Monro and Valvoline both describe their markets as fragmented, with room to consolidate³⁵.

Car washes draw buyers for a different reason: memberships. Mister Car Wash ended 2025 with about 2.3 million Unlimited Wash Club members, who produced 76 percent of its wash sales, in an industry it calls highly fragmented⁶.

The buyers you are most likely to hear from:

• Tire and service platforms backed by private equity. Big Brand Tire & Service, a Percheron Capital company since 2021, agreed in July 2026 to buy Belle Tire, a Midwest chain founded in 1922⁹. CenterOak Partners completed a majority recapitalization of Grismer Tire & Auto Service, a second-generation family business with 28 Ohio locations, in April 2026¹⁰.
• Public and franchise operators. Monro counts buying one- to four-store operations as part of its new-store plan³, and Valvoline agreed in February 2025 to buy Breeze Autocare, which operates mainly as Oil Changers⁵. Franchisors change hands too: Monomoy Capital Partners completed its purchase of Jiffy Lube from Shell for about $1.3 billion in July 2026¹¹.
• Fleet repair and towing specialists. New Mountain Capital made a majority investment in Amerit Fleet Solutions, which has more than 2,500 field technicians, in January 2025¹². Sounder Partners launched Uptime Fleet Services in February 2026¹³, and Access Holdings took control of Reliable Towing in the Pacific Northwest in August 2026¹⁴.
• Car wash platforms and family offices. Leonard Green & Partners took Mister Car Wash private in May 2026 at an enterprise value of about $3.1 billion⁷. Spotless Brands, an Access Holdings company, bought six-site Pete's Express Car Wash near Philadelphia in November 2025¹⁵, and Argosy Private Equity backed six-site Mr. Splash Car Wash in Madison, Wisconsin in January 2025¹⁶. Links Car Wash, owned by the family office Back Nine Equity, agreed in July 2026 to combine with Woodie's Wash Shack¹⁷.
• Real estate investors. Car washes were the largest industry in Essential Properties Realty Trust's portfolio at the end of 2025, at 13.7 percent of annualized base rent, with automotive service at 8.0 percent⁸.

Most buyers split revenue into two numbers: how many cars come through and what each one spends. Valvoline credited its 2025 same-store growth to a higher average ticket, from premium products, pricing and services beyond the oil change, and to more transactions⁵. Expect to show both by location and month, and how much ticket growth came from price.

Technicians come next. Some shops pay by the hour and others by the work completed², and a buyer will want your pay plan, billed against paid hours, tenure and turnover. Certifications are proof of the bench. ASE certification takes a passed test plus hands-on experience and must be renewed every five years²¹. ASE's Blue Seal of Excellence goes to shops where at least 75 percent of the technicians doing diagnosis and repair are certified and every service area has a certified technician, and ASE checks eligibility each year²⁰.

Fleet and commercial accounts add steady volume, and for fleet repair and towing companies they are the business. Buyers will ask for each contract's terms, tenure and share of revenue, and for towing, which municipal or police rotations you hold and whether they survive a change of owner.

The numbers buyers usually ask for first:

• Car count by location and month, with the share from repeat customers
• Average repair order, split into parts and labor, with your pricing history
• Technician headcount, tenure, pay plans and ASE, OEM and Section 609 certifications
• Gross margin by category: tires, maintenance, repair and fleet work
• Revenue from each fleet or commercial account, with contract terms

For an express wash, the membership program is what a buyer studies first. Members can usually cancel at any time, and Mister Car Wash lists why they leave: price increases, quality problems, seasonal use and household budget pressure⁶. It also sells most memberships in the first half of the year⁶, so buyers want a full year of data. Members kept with deep discounts count for less than members who renew at full price.

Format matters too. Mister ended 2025 with 485 express exterior sites and 63 that also clean interiors⁶, and Spotless expects about a third of its new Philadelphia-area sites to be flex washes that add optional interior services¹⁵. Full-service washes carry more labor, so buyers look hard at staffing and margins.

Then the site and the tunnel: traffic, visibility, stacking room, competition, and the age of the conveyor, dryers, pay stations and reclaim system. After buying a wash, Mister upgrades tunnel equipment and site flow and adds member-only lanes⁶, and a buyer will take the cost of any such work out of the price. Water also matters: Mister warns that drought and limits on water use can restrict supply, and that sites may need wastewater or stormwater discharge permits⁶.

The numbers buyers usually ask for first:

• Members by site and month, with sign-ups and cancellations
• Member share of wash sales and average revenue per member
• Cars washed per site per year and peak-hour throughput
• Labor, chemical, water and utility cost per car
• Equipment list with install dates, plus ownership or lease terms for each site

Most of these are familiar to owners. The difference is that a buyer finds them all at once, during diligence.

• You are the lead technician or service writer. If the hard diagnostics, the fleet relationships and the customer calls all run through you, the buyer is paying for your labor, and you are the one leaving.
• Short or locked leases. A lease with a few years left, or one a landlord can block on a sale, undercuts a site's value, especially a wash that cost millions to build. Mister notes that it cannot assign or sublet leased sites without landlord consent⁶.
• Deferred equipment. Worn lifts, an aging tunnel controller or outdated scan tools become repairs the buyer subtracts from its offer.
• Environmental unknowns. Old tanks, floor drains and thin waste records delay closings. Mister reports that some underground tanks at sites it acquired remain on leased properties, with removal and possible cleanup still ahead⁶.
• Concentration. One fleet customer or referral source with a large share of revenue is a risk the buyer will price in.
• Numbers that do not tie out. If your shop system, point of sale, card processor and bank deposits disagree, diligence slows and trust drops.

Federal rules set the floor, and states often add their own. Expect a buyer to ask for records on each of these.

• Vehicle air conditioning. Anyone who services a motor vehicle A/C system for payment must be certified under Section 609 of the Clean Air Act through an EPA-approved program²². Technicians must use certified refrigerant handling equipment, shops make a one-time certification to their EPA regional office that they own it, and shops keep records of each technician's certification and where recovered refrigerant goes for three years²³.
• Used oil and fluids. EPA's used oil standards in 40 CFR part 279 apply to repair shops, fleet maintenance sites and quick lubes, and call for labeled containers and tanks in good condition, prompt spill cleanup and transporters with EPA identification numbers. States may be stricter²⁴.
• Underground storage tanks. Federal tank rules cover systems storing petroleum or certain hazardous substances with at least 10 percent of their volume underground, and regulated tanks must be inspected every three years²⁵. EPA notes that most tanks installed before the mid-1980s were bare steel, which tends to corrode²⁵.
• Site history. Under the federal Superfund law, current and past owners and operators can be strictly liable for contamination at a property²⁶. That is why buyers and lenders order a Phase I environmental site assessment, the usual way to complete the All Appropriate Inquiries that can protect a new owner; EPA's rule recognizes ASTM's E1527-21 standard for that work²⁶.

Real estate comes first, since many owners hold their buildings. You can sell the property with the business, keep it and lease it to the buyer, or sell it to a net lease investor in a sale-leaseback. Essential Properties made 95 percent of its 2025 investments that way, usually with initial lease terms of 15 years or more, renewal options and rents it aims to set at or below market⁸. Buyers use the tool too; Spotless funds part of its growth with sale-leaseback proceeds¹⁵.

Rollover equity is common when a private equity firm is building a platform. At Mr. Splash, both co-owners stayed on as significant owners¹⁶, and when Mister Car Wash went private, members of management rolled over part of their stake⁷. A second payout can be worth more than the first, but only if you trust the plan.

Earnouts and seller notes cover what is not yet proven. Mister disclosed an earnout from its 2021 purchase of Downtowner Car Wash, with one payment when a new wash received its certificate of occupancy and opened, and annual payments tied to financial targets⁶. When Driven Brands sold its US car wash business to Whistle Express in April 2025, $130 million of the $385 million price was a seller note⁴. Keep any earnout simple, measurable and short.

Then the brand and the team. The Pete's Express sites are moving to the Flagship Carwash brand¹⁵, while Telle Tire said it would run Jim Whaley Tires as one of its core brands¹⁸, and the Links and Woodie's combination will operate under the Woodie's name, with the founder keeping a role through a company that holds the brand¹⁷. Strickland Brothers kept every LOF Xpress employee in July 2025 and made the former CEO its CFO¹⁹.

If you run several locations, do this site by site, because buyers will compare them.

• Build a monthly report for each location: car count, average repair order and gross margin, or for a wash, members, cancellations and cars washed.
• Tie shop management or point-of-sale data to bank deposits and financial statements, and separate personal expenses.
• Document roles, tenure, pay plans and certifications, and put a manager in charge of daily operations.
• Collect environmental records: Section 609 certifications and equipment, used oil and waste hauler paperwork, tank registrations and inspections, and discharge permits²³²⁴²⁵.
• List major equipment with install dates and condition, and repair or budget for anything near the end of its life.
• Review each lease for term, renewal options and assignment rights, and talk to landlords before a buyer does.
• If you own the real estate, decide whether to sell it with the business, keep it or sell it separately, and get an appraisal.
• Put fleet, commercial and towing agreements in writing, and check which need consent to transfer.
• Consider a Phase I site assessment on sites you own before a buyer orders one²⁶.
