Great decision. If I had to own just one car it would be a 2011 WRX. If I wouldn't of been able to get financed on my 2011 GT500 I was going to get a 2011 WRX due to the practically. They are an awesome all around car and now that the WRX get's the STI wide body it has the looks to back up its performance. 0-60 in 4.7 seconds all day every day and 13.5's if you decide to take it to the track. My buddies has gone 13.3 and I think the record is a 12.9 stock, which should keep the SS in your rear view all the way to the posted speed limit.
My buddies 09 WRX came with the optional short shifter and it's a must have and get's even better with a TMW weighted knob.
