Two years with my XFIREX...I'm still a happy driver! When I bought my XFIREX, I bought it for the one of a kind design and style, the auto-deployed spoiler, the Euro interior and the Mercedes platform inside it! The speed comes in demand later but was not really a priority if you are not racing with other cars. It is considered a sports car because it performs better than regular cars. If you're racing your Crossfire...spend money on it to compete at a higher level and the upgrades are already available in the market.
