Tim: Hey, if you end up having to keep BOTH cars, at least you will have one with stripes and one without.......best of both worlds!
I'd go around to some car dealers if I were you, and look for a nice blue color and throw some white stripes on it. Wimbledon White is nice on the right car (I especially like them on SPF's dark Green - Malachite, that they use), but I don't think it's as popular (for resale) as regular white. Then again, if you want the car to stand out a little bit......that might be the way to go!
Good luck! ......It would be a shame if you had to keep them both!
