My heater core went out when the car was 18 months old.
If anyone out there finds a Y88/WS6/W72 auto with a patched seam in the pass side wheelwell, it might be my old car. JK fixed it for me and made an L cut to get to the bottom clamp rather than remove the bottom bolts.
Also from the factory, if you lifted straight up on the drivers side rear spoiler cap it would lift off. All you had to do was put it back and it stayed, never came off on its own.
Strange Y88 things.
