I love my 2005 Limited Roadster, take a look at the TSB section there a few gremlins that can be fixed under warranty. If the car you are purchasing is out of warranty, then they may be a bit expensive. Finding a good competent XFire Tech is a bit hard but not impossible. If you are looking for speed then take a look at the SRT6, 330 HP Supercharged MB AMG engine, the Limiteds are built on the old MB SLK 320/R170 platform 215 HP. All in all the Crossfire is a big bang for the buck at todays prices and the SRT6 is a really big bang for the buck.
