Audi when first released the TT had the spoiler as an option and after a few high speed crashes(customers, lawsuits) they recalled all TT's without the spoiler and installed them at no cost. The Crossfire has a similar rear end to the AUDI TT, hence the spoiler. Cars with that kind of rear end generate more lift than some other cars, hence the need for the spoiler. The car is actually an Mercedes SLK - same chassis, Mercedes motor, except that it's built by Karman Ghia. The interior uses too much cheap plastic to keep cost down.
