Nice business if you can get it.
I went to a police auction where a lot of the recovered stolen property which went unclaimed was being sold along with their surplus vehicles, office furniture, etc.
There were loads of T-tops and naturally the used parts T-top dealers were there to pick them up at rock-bottom prices. They all knew each other.
They knew exactly which car model each one would fit and this had become an increasingly more detail-oriented business.
When a theft victim showed up to a used parts dealer, if the dealer did not have the exact part in stock (or in his network) he would tell the victim that it would take a few days to come in.
Basically, when an actual willing buyer was identified, if the part was not available already, it would be stolen to order from a compatible vehicle by street thieves who had become more detail-oriented over the years themselves.
Right to repair has the downside of not checking for stolen parts like that. Which is why it isn't the black and white issue most people think it is.
You have to log ID, provide a small payment and it logs the VIN the item is being tied to as well as having a list of stolen parts.
No anti-repair steps needed so you can stop shilling.
The other business opportunity, complementary, is security devices to protect your parts, extra tricky huge locks and their lock-picking sets, secure parking lots along routes at premium fees and then of course a special platinum lounge thing with concessions. And marking parts with license plate numbers.[1]
Great alignment of incentives among the two excellent business opportunities.
[1] That last one I saw in Chile in fact like in 2001, stamping license plates on mirrors. Worse mirror of course. They also did windows, you wonder why, guess they had a glass stamping machine and not enough customers, wanted to get more money from the same customers. The dentist thing basically.
