See my previous post about my personal take on the Crossfire's reliability.
As Sonoronos mentions, the car isn't cheap to maintain: tires, yup, they're not inexpensive, expect to pay roughly around $250 each for the exclusive brands (Pirelli, Michelin) for just the rear tires alone. Oil changes aren't cheap unless you can do them yourself. The car requires synthetic 0W-40. Mods are available but expensive compared to what you may be used to paying.
