INSIGHT

Car Wash Is Four Different Businesses

'Car wash' is four distinct businesses with different economics and risks.
Jack Carr lists self-serve, in-bay automatic, express tunnels, and full service as separate models that require different evaluation.

ADVICE

Pick Model Then Site Before Diligence

Do match the model to the buyer and site before starting diligence.
Jack Carr warns self-serve needs maintenance, decent area, and at least one or two employees despite low labor label.

ADVICE

Don't Treat Self-Serve As Passive Income

Avoid thinking self-serve is fully passive; maintain appearance and equipment.
Neglect leads to vandalism, losing traffic, and attracting low-value customers who damage bays and leave a mess.
