oh and to answer your question noles,some cars you can beat are, low to late 90's mustang GT's (with no mods of course), you could beat a bottom of the line srt4 for a short distance, you can stomp just about any family sedan, I personally have beat an srt4,mitsubishi eclipse turbo,infinity g35 (4 door auto tragic),aftermarket turboed ford probe with a klze,90 mustang gt, subaru wrx impreza (2003ish), so ya there are plenty of cars out there that the n/a xfire can handle easily

just enjoy your awesome car!
