 Update:  at 3300 miles on the car my wife was at a stop light.  She stepped on gas to leave the stop light, the motor raced to 6,000 rpm's and engine roared but the speed stayed the same.  This scared the hell out of her, she pulled into a parking lot and turned off the motor and waited a few minutes and drove home.  I drove it for 30 minutes trying to replicate the problem. This has not happened since.Driver's seat:  I needed to buy a cushion to make the driver's seat comfortable.  It did not provide good back support prior to using the cushion.
