Too much to reply to here guys, but thanks for all of your help.
Looks like I'll be picking up a 370Z within the next month, a couple of issues with the Challenger have come up since I first posted and my gut feeling tells me the thing is a ticking time bomb and it may be worth it to just flip it before I pick up too many miles and it isn't worth much.
This forum really has been great and given me some good insight into the car which allowed me to weigh the pros and cons of the decision. Will post pics of the old and new rides when I pick it up, currently in the middle of a move so may be delayed.
One last question...red or white?
