Hi Dubbell
Firstly I cannot answer absolutely on the warranty. I would have thought though that if you have the certifcate your local XRAY dealer could help you but I am not sure how it works - never needed it!
I assume you can look at the car before purchase. If it has had only one meeting then it should look brand new all over; do the belts look brand new? The gear or ball diff should be silky smooth. The underside of the chassis plate should lack scratches, dings etc- which is not say there could not be a scratch but it should look pretty much as if it has just come put of the box - especially if the run was indoors.Rotate the wheels - everything smooth? If you can run it on the bench with the motor then check the driveshafts. If it has had a smash and there is a bend, you will see it on the bench.
Ask the guy why he is selling it after one run !!
slide your ride height guage under the rear of the chassis and check that the 2 wheels are leaving the surface at the same time, or close to. Ditto the front. If there is a big difference you might wonder why. Has he smacked it and tweaked it, or maybe he is just lousy at setting up a car
