I do my own work, but have to go somewhere for state inspection stickers.
The state capped the price at eighteen bucks in 2001 and hasn't upped it since. It takes an honest half hour to do the job, so shops lose money on each one they do hoping to get collateral repair work out of what they find wrong.
So I use chain tire stores with pretty good results. I know the book, briefly used to do inspections (at the worst chain around, LOL.) They probably look at me as a deadbeat for wasting their time, never getting the work they recommend, never using them to get my car up to par for a sticker.
They also spend all sorts of time entering my car into their database, they track me by phone number. I don't have the heart to tell them as soon as that sticker goes on, the car's on Facebook Marketplace. So they ask me about it the following year, even send me postcards that my beater needs an appointment.
But, yeah, you have to have a nose for deadbeats in any business. Chain stores have a philosophy of scraping the dirt for business so they keep answering my call.
