If a particular car has been such a chronic headache that it gets you pissed off looking at it, sell it for whatever it gets and move on to something else. If it's run well for you and you still enjoy what you originally liked about it, then what's to second guess about your decision? Most SRT-6's seem to fall into the later category from what I can see and don't stack up too poorly compared to the competition on the headache factor. I never met a post-1973 VW that didn't have electrical issues, and their dealers make Chrysler service look good. The first generation Boxster oozed oil and half had to have their engines replaced. 2001/02 M3 was cited on the Bimmer forums as having the "Engine of Damocles" which BMW only addressed under threat of litigation. My friend's new twin turbo 335 Vert has been in the shop 5x already for warranty issues that the Techs never seem to be able to appropriately address.

Fiero GT was a $8k car that had 135hp in its best year, and only the last year had a half-way sporty suspension. Northstar equiped Allante actually has a following and decent resale given that it's very dated looking and not a terribly attractive car. I don't see the comparisons holding to an attractive 330hp sports car. If it's solely reasale that ticking you off, the wholesale car market is super-soft and every new car dealer is offering crap trade-ins on almost every used car these days. Pick up a copy of Galves and check it yourself. Most cars that sell on EBay go for pretty close to wholesale pricing. That's why people shop it.
