I can't say I've ever seen a junkyard like that in today's market.
Of course most people don't "fix" cars anymore. If the part required isn't at the dealer then it is very likely the car will be "totaled" as the cost to repair will exceed the used value.
A 2003 VW Golf Diesel that ate its own transmission comes to mind. ("Self-adjusting clutch" NOT one of VW's better ideas.) A replacement was $3800 - USED. Car value then about $2800.
The VW dealer/repair shop ended up owning that one for the price of $1 - and forgiveness on their storage cost and "scoping out."
This is how they continue to sell cars now. Car breaks, and the typical auto repair now is at least $450. Then they say, but we can get you into a lease of a new car, or even a 1-year old lease turn-in for $XXX/mo.
Leasing was their big trick to make payments affordable to continue sales. I think they are just about out of tricks. The price of cars is getting crazy. Can you imagine how much a Model-A truck would be today if it were the current model? You can spend $50,000 to $80,000 for a pickup now days.
I used to buy parts from junk yards for my first few cars. I always thought they were great.
