Actually I have been driving it although the last few weeks we have had some snow so it's been parked. I agree it drives great! Runs straight down the road and the original six purrs like a kitten. Not sure about highway speeds I need to hook up temporary tach and check the RPMs. Steering issue is related to turning it around in a tight foothills driveway, I would not want to give up feeling it has on the road. PB and duel master is a safety concern.
