I’ve recommended Mark several times and have always had very positive feedback. A mate of mine who no longer posts on the forum[:^)] travels from the Notts area to have his car serviced by Mark.
As to the cost of the cambelt change. I know from personal experience, that a cambelt can be changed in well under an hour by a mechanic who really knows what he’s doing. Mine was done by a very good mate, in my driveway, on an Eastern region techday. He was also advising other people on a variety of tasks but the job was completed very smartly.
RE The Gear stick, by wobbly do you mean vibrating a bit?
It is normal for it to move, because their is no linkage to damp any vibration like there is in most cars. If however the stick is loose, that is not normal.
