Assuming you aren't going to turn around and use the money to start another engine project, sell away... Don't know about price though, but you know what you paid for all that stuff. As for the doors/lights, I wouldn't see why you'd sell them if you like them, and plan on still driving this car... I was under the impression the strosek tails weren't the easiest things to get a hold of too? Price *seems* reasonable for those parts at least.
