I'm looking to get an '06 wrx, car has a little work to it, but nothing big. air intake by COBB, turbo back exhaust thoubh im drawing a blank on the name, BC race suspension with Camber adjustment from soft to hard and an access port, though it was never tuned. Dont know why it was ever tuned, but its there. also comes with stock suspension, stock exhaust system and a spare set of wheels and tires. originally he was asking 18,500 for it, but had no bites so he lowered it to 17,500. I talked him down to 16,500. Car has just over 71k on it, 60,000 tune up was done, reciept to show. In any event, I have to get a loan for it, but I'm in a pickle. I dont know i its a TR or a base model, how can i tell the difference? new to the whole WRX thing, but both models look exactly the same. Thoughts?
