I’d forgotten about a couple of cars my dad had years ago. 78 Buick Regal with turbo. Engine was worn out at 50k miles and when the turbo kicked in it smoked like it was on fire. Dealer said that the cam was worn nearly flat and the cylinder bores were badly grooved, and none would be warranty covered since it was a known materials defect. So it left for someone else to mess with. Then in the later 80s a Lancia Zagato. Wasn’t a bad driver but you couldn’t get individual parts. When the horn push quit working dad went to have it fixed. Lancia would not sell the part required, you had to buy a complete steering setup including the column, connecting shafts and steering rack, couple grand then to replace a $10 contact kit.
