As the title says. When I was younger and lived in Warsaw, my family sometimes used to drive by a junkyard near the Vistula. They mainly dealt with boats, but also had some cars. One of them was a big old pink sedan, I think it was a '49-'51 Ford. It was hard to tell the trim, because it was stripped clean of anything of value. The only thing left was the throughoutly rotten body that looked like its last good times were in the 80s or even 70s. There also was (or maybe still is) a damaged VW Phaeton in 2018 at a different yard dealing with damaged UK market cars. Not sure about the trim. In terms of internet listings, I've once seen a 1975 Cadillac Eldorado convertible being parted out in Silesia, and a guy (can't remember where) who had 5 or 6 1979-1991 Ford LTD wagons for parts.
One time I saw a 1988 Buick Reatta in a junkyard. I couldn't use most of the parts for my own Reatta as its a 1989 and the interior is blue instead of red like the one in the junkyard. I did take some buttons as the ones in mine are worn out and unreadable. If the car in the junkyard still had a touchscreen and/or gauge cluster I would have bought those to have as spares though.
Not much, other than a few 60s fullsize sedans that looked like they were used in banger racing. The junkyards around me are relatively boring tbh.
Finally I can talk about this thing I saw, so like a year or two ago me, my dad, and I think my step brother Justin went to Gary's U-Pull-It and I saw this Pontiac Firebird done up just like Dale Earnhardt's car
