I have had my XFire for a year now and NO problems. I drive it like I stole often and it begs for more.
Regular maint. you can do yourself. A lot of people on here use the ROTEX GOLD brakes pad as the originals create an incredible amount of brake dust on the fronts. Any good ceramic brake pad will work just as well.
The car is such a quantum leap from your Mustangs and Camaros. No comparison. You will get a lot more car than your are paying for at current prices.
RUN - don not walk and get one right away, you will not be sorry.
