The Investment Thesis

The case for car washes as an institutional asset class came together in the mid-2010s and reached full pitch by 2020–2021. Understanding what that thesis was — and which parts of it still hold — is the right starting point for anyone underwriting a deal today.

What attracted institutional capital

Five characteristics did the work:

High gross margins at the unit level. A mature express exterior site runs gross margins in the 65–80% range. Chemicals, water, electricity, and tunnel maintenance are real but proportionally small against revenue. The format is engineered for throughput, and once the tunnel and pad are paid for, incremental cars carry very little marginal cost.

Recurring revenue through unlimited memberships. This is the single biggest change in the industry over the last fifteen years. A site with 60–75% membership penetration starts to look more like a subscription business than a retail one, with all of the valuation implications that carries. It also smooths weather and seasonality, which historically were the dominant variance in wash businesses.

Owned or controllable real estate. Most operators own the underlying land and building, or hold long-term leases on purpose-built sites. That creates two distinct value pools — the operating business and the real estate — and gives sponsors structural flexibility (sale-leasebacks, separate exits, OpCo/PropCo splits).

Fragmentation. Going into the consolidation wave, the U.S. car wash market was roughly 60% chains and 40% independents, with the chain side itself fragmented across hundreds of regional players. That’s the textbook setup for roll-up strategies: enough scale players to validate the model, enough independents to feed a long acquisition pipeline.

Operating simplicity at scale. Express tunnels run on a small labor footprint — often three to six people on shift — and the operating playbook is repeatable across sites. That makes the unit replicable in a way that, say, restaurants or full-service auto are not.

What the bull case got right

The membership transition was real and was the right place to focus. Operators who pushed early on unlimited plans built businesses that valued at multiples that made no sense as retail comparables and made considerable sense as subscription comparables. The fragmentation argument also held: platform-plus-bolt-on strategies executed throughout 2018–2022, generating real consolidation premium for early platform builders.

Real estate value compounded the equity story. In a low-rate environment, cap rates on triple-net car wash properties compressed meaningfully, and operators who owned their dirt captured both operating EBITDA growth and a real estate revaluation tailwind.

What’s already been arbitraged away

This is where new entrants need to be honest. The original “buy cheap independents and recap at a roll-up multiple” trade is largely done, at least at the easy end of the curve. Several things have changed:

• Independents know what their businesses are worth. Sellers price in the consolidation premium, and brokers know who the strategic buyers are.
• Multiples have compressed from the 2021 peak. Reported transaction multiples reached the high teens for premium platforms during the 2021 frenzy. They’ve since reset to a more defensible range, but the reset itself was painful for funds that underwrote near the top.
• Site supply has caught up in several metros. Phoenix, Houston, Charlotte, parts of Florida, and other early-overbuild markets are now saturated enough that new express sites cannibalize rather than expand the market. Saturation analysis is no longer optional in underwriting.
• Operating execution now matters more than financial structuring. When you could buy at 7x and sell at 15x, structure carried the deal. At 9x in and 10x out, the operating delta between top-quartile and median operators is the entire return.

What’s still durable

The membership economics remain compelling for well-operated sites in well-chosen locations. The fragmented long tail is still there for patient buyers with disciplined acquisition criteria. And the real estate component still provides downside protection that pure operating businesses don’t have.

What this means in practice is that the thesis is no longer “car washes good, buy them.” The thesis is “site-level performance varies enormously, operating execution determines outcomes, and the next decade rewards underwriters who can distinguish between the two with data.” That is a different — and more demanding — investment posture.

How to read the rest of this series

The following pages take this thesis apart into the specific decisions that determine returns: what format to buy, what unit economics to underwrite, how to evaluate sites, how to evaluate membership quality, how to source and integrate acquisitions, and how to exit. Each of these decisions can be made well or badly. The differences compound.
