I have an 07 P with 25,000 miles and would definitely buy one again for all the reasons cited here -- nice pickup, good handling, easy to park, plenty of interior room, very reliable, excellent mileage (46 MPG over life of car), car pool-lane stickers and tax credit (sorry -- couldn't resist), comfortable ride.

You should definitely take a long trest drive, though. Although I find the drivers seat to be quite comfortable, even on day-long drives, several posters in this forum have complained that it hurts their backs.
