Howard,
I think you really need to go to a good dealer/service agent - say BHM or Richard Thorne if in the South, Newtown Motors if in Wales, The factory if Midlands / North or Russell Patterson if in Scotland. (Other people may have other suggestions, these are just my thoughts) Then DRIVE a selection of new and second hand cars and ASK the dealer all your questions. The above will all know and be happy to chat!
Driving the cars will make your mind up far quicker than reading the opinions of people like me!!!!! it is after all your choice!!
Cheers!
