I just picked up my first Evo about a week ago from South Coast Mitsubishi. Its a '15 MR with the terrible seats. Unfortunately I couldn't find a deal good enough on a '14 anywhere. Anyhow I live in San Marcos and look forward to learning more about this platform.
I traded in a focus st for the car, but the aftermarket support really wasn't there for that car. There were a few 400whp ST's running around, but that was about the most power people were able to get out of them. I've owned everything from an S2k to STI to Golf R. So far the Evo (with the exception of the seats) seems to be the best out of the box platform.
I've already got sidemarkers on order to replace the hideous chrome things in the fender, and I'm looking for '14 pb mirrors and recaros to fix what mitsubishi screwed up for the '15s.
