I bought an 07 TR about a month an half ago. Traded in a 2002 Sentra SE-R Spec V. My Nissan was quick but the WRX is just plain fast. I love it. Wish I could've got an STi, but like I told the dealer, my STi money is my 11 yr old daughter. Wouldn't trade her for anything.
I don't post a lot, because I got really turned off by some of the Nissan boards where people build humongous post numbers by making stupid comments or telling everyone to search.
yeah, do not hesitate to post, there is a lot of gathered knowledge in this area, I used to use NASIOC and some others, but they suck in comparison, they are generally assholes, we are not, so feel free to ask anything you wish, we will not flame on ya....too much
