Hello all, I got to have a great test drive in a P90D, I'm looking for the 90D, but got a try in the P90D... What a great car, however I found one problem, after about 30 mins driving, my lower back was aching.. I couldn't quite find a comfortable driving position, this was the only downside to an otherwise great test drive.. The only part of the seat I couldn't find a comfortable position was where the seat back meets the lower part.. The question is, has anyone else experienced this or am I just unique.. im going to have another test drive at the end of the week as this could potentially be a deal breaker.. This car had the upgraded seats. I tried lots of different position and tried all the lumber support. Any feedback would be most welcome. Thanks in advance.
