Thank you all, Dealer says it was all ok on their test drive.
Glad I turned around after 1/4 mile & took it back to show them the speedo gross over read. I now understand why the car had 129 miles on it as have done an extra 20 or so & it now says 218 gues it thinks the wheels are going around very fast.

John +4 that is a little gem of an article, when you pull the top of the side screen does it mean inboard or aft?
