Love the PBP! I am planning to place an order for one next month. Just started shopping dealerships in the Bay Area and best price I've gotten is $250 under invoice for the STI.
Also, I almost couldn't believe it but a dealer called me last week and told me he had a black STI that just came in and asked if I wanted to come in for a test drive!! I immediately left my office, drove 30 minutes to the dealer, where he proceeded to take me on an hour long drive in a beautiful black hatch. These guys don't get a lot of STI's obviously. Most every other dealer won't even let you drive it because people want them with no miles. I put 30 on this one, and treated it like I was going to buy it (went over 4k rpm 2 or 3 times, but never WOT).
I'd only driven the WRX before, and based on everything I'd read was questioning whether it was worth spending the extra 8k for the STI. Not anymore. :-)
