yeah, fair enough. unfortunately, the sad reality is that you can never get your money back out of a car, especially when it comes to parts and labor. if this was the case, id be rich. the only cars that this works on are super rare cars, like the toyota 2000gt, copo muscle cars and antiques. MK3 supras dont fall into any of those categories. however the MKIV is one of the few "average" production cars that is an exception to the rule "cars are poor investments"
