My MS3 stayed stock, minus a K&N filter. In the 2 years and 27K that I had it, all I ever had to do was change the oil, and replace the front tires (Baltimore pot holes after last year's crazy winter destroyed them). I looked at the 08 WRX when I bought my car and wasn't a huge fan. I thought the interior of the MS3 was much nicer. You also got a lot more options for the money. I understand the WRX has changed some since the 08 model I looked at.
