I wanted to buy one these cars myself partly because I have a big block .15 in need of a home...then I looked at the cost of replacement parts. Ouch! Guess I'll stick with my NTC3 and morgage payments.
In case your wallet is thicker than mine, I've heard that the Impact is a very good performing car with decent quality.
The Impact is not for the meek. Parts are not hard to find at all. Expensive as hell though. Very nice car but a tire truer will set you back big time along with all the necessary set up tools which are a must have on cars like this. Yes an MS edition engine is a must. I had the EV3 MS and it screamed.
