I just bought my XRS, it has less than 600 miles on it. I plan to at least get past the break in period before i start doing any serious performance mods on it. I do have a few universal mods on the way tho as far as styling; tints, interior LED ambiance, 18" rims, HID fog lights, brake caliper paint etc
The mods will come as I get money for them.
As far as performance mods in the future, I don't really think of my car as a performance vehicle, more like a "luxury-compact"

slash mini-Camry. If I do any upgrades though, I will probably be looking at intakes first. I don't want to do anything to force me to start using premium fuel, or to greatly reduce MPG, such as a turbo/super charger.
For an a-b commuter, my XRS already has more than enough power for me any way, especially for passing assholes on the high way who drive real slow in the passing lane, then flip you off when you pass them on the right. TORQUE BABY
