I wouldn't sell the car because of any danger issue, but...

Very hard question cause any car I would want would be at least double the price of the crossfire, because anything else would be just a too huge of a downgrade to handle...

CL55 V8 Kompressor... I know it is no where near as flashy, but the price on these is great and I driven one recently and I can say I liked it quiet a bit... and it is something I can afford... one can be had for around 45k which was only a few years ago was 100+... I could of said SLR, but it would not be possible for me at least not yet...

Caddy XLR... Always wanted a hard top convertible since they were released, but never liked the slks and the sl was just to common place... In some ways this car is similar to the crossfire as it has a really rapid price drop and it is quiet unique... also can be had for high 40s low 50s.
