1989 Chrysler Conquest TSI

This is it! A fine example from the last year of production of the Chrysler Conquest/Mitsubishi Starion! This car has been garaged for the last few years after having been completely repainted. The car looks amazing and gets stares everywhere. It sounds as good as it looks and although the engine has some minor damage, it still hits boost hard and will spin the tires easily. This car is a blast to drive!

Here's a video overview of the car:

I would recommend towing the vehicle if it's going between states, but the car does run and drive great. The car is sold as-is with no implied warranty or returns. I've tried to be as open as I can about this car but please feel free to ask additional questions via email.

This car has a lot of high quality upgrades and runs and drives but has a few issues that I will call out first…before we get to the good stuff.

Problems with the car that I know of:

1) Power steering pressure hose is leaking a small amount. A new hose will be provided with the car.

2) Engine has low compression (40psi) in cylinder 1. Smokes on boost but otherwise runs and drives great. Per a leak-down test, It likely just needs new rings because it is an original untouched bottom-end. Car does not overheat and I would drive it anywhere.

3) There is an small area near the rear bumper where the painter didn’t spray properly that you can see some of the red that the bumper used to be. The bumper was replaced because the car had a minor tap from the previous owner.

4) HVAC system needs to be inspected as the controls were relocated to the glove box and the blower works but the A/C doesn’t seem to work.

5) Cruise control actuator is broken.

The GOOD stuff!
