So do any of you Plus Four chaps get this…

On lifting off the throttle in any gear but particularly noticeable on a motorway run, I get this harsh vibration through the seat.

It’s a new car….well 500 miles.
Any thought?

Hi Viper, Auto or Manual box?. Assume the vibes seem to be coming up from the rear of the car? if so I would tend to look at the prop shaft or rear drive shaft areas.. Think it wise to let the dealer look at it... We have a Plus Six, but the drive train geometry is basically similar, and its vibration free.. only get the odd clonk from suspension working over the numerous pot holes...

Thanks Dave.
It’s a manual. I was thinking maybe the prop shaft as I had similar with an Etype but that was under hard acceleration.

Will send it back to the factory. I just wanted to make sure it wasn’t standard.
