Go to my recent post to see the Operating Cost & MPG for my 2007 Coupe. Car has been really consistent over the years in its gas mileage and op costs have been reasonable, impacted only by minimal miles driven in a specific year and/or a major expense (e.g., tires). You'll see per the attached spreadsheet in that post that many of my expenses are things that weren't necessary, but were things I wanted to do.

So where in NC are you located? There are quite a few XFire Owners in the Carolinas and, if you asked, you'll probably get recommendations on where you can take your car for service if anything major popped up.
