I kinda agree with Bob here, and the:
"Injector Calibration / Hot Swap (1996-2002, Manual, Stage 1, Hot Swap) $776.00"
is misleading because you got $600 of that money back when you returned the injectors from the Hot Swap. The way you posted it makes it seem like that's what you spent on the car.
Also, there is no 100k timing belt for these cars.
Still, you did a lot of work to it, which should count for something, and that Growler did the work says even more. Good luck with the sale, but I would not count on $2K for it with a blown motor.
