Toyota Supra Turbo 7M-GTE with R154 5-speed
Welcome to the forums.Actually I know the history pretty well. It's a one owner car (mine) and all stock. But back in the day, I could "point-and-pay" and didn't really pay that much attention to what the dealer did for repairs HG-wise. I'll recheck my receipts more closely.
Interesting that your car sat for 8 years. Mine has sat since 2007 because it was burning coolant but passed compression checks etc. The assumption was coolant erosion into the chamber of cylinder (#6?) because exhaust gas was found in the coolant. Was told to keep driving it but I was afraid to so it sat. Big mistake. Now the tranny has issues going into reverse, coolant light is always on no matter how far topped off, etc.
