I would pay that simply because the car has been driven. I would rather have a driven GN with higher miles on it than a low mileage one that has sat for years.
Call me stupid but I ended up with the latter of that statement. In the last six years my GN had been driven one thousand miles. Thats it, then it sat and sat and sat. I paid 10K for mine knowing full well I would need to do some tuning to it.
After replacing the full exhaust system, fuel pump, fuel filter, injectors, IC hose clamps, brakes, oil, coolant, tranny fluid, tires, intake cleaning (thats expensive), boost vacume line, cleaning an oil mist off of the IC hose, spark plugs, wires, EGR valve, and now a steering wheel horn trim ring. The car now runs great and can spin the tires again without worrying about the motor falling out.
My car has no rust but is in dire need of paint. Since it sat for so long the clear coat is flaking and cracking all over the place.
Jeffgn6 has a nice one that I should have took instead. His is in the same price range but with a little more miles on it. The paint is great and the car is an 11 second car which is what I am going to make the one I have. His car is driven so I know nothing would be dry rotted or varnished all to hell on it like mine was.
