I got a print out from my dealer that says priced order confirmation at the top, as I was there to check the status of my car, and test drive the RT they had on the lot. It says $1300 for the gas guzzler tax, and it says $1700 on the print out I got in July when I ordered the car. Perhaps since the manual get's slightly better gas mileage? I originallly ordered an automatic, so that could account for the difference.
