My mechanic is not a Gen 7 engine specialist. However, he is an excellent mechanic (as opposed to what I would call a "fitter", who works at a main dealer). I've known Kev since the early 60's, he has approaching 50 years experience working on all marques, and can be trusted to do a good job at a very fair price. I should mention he is not VAT registered, so that's 20% off the bill for starters. He's worked on quite a few club members cars over the years, so is familiar with the Gen 7. How much engine work..I don't honestly know.
One current member who will only use Kev for repairs is SlickCelica.
I called in to see him yesterday morning, to book one of my cars in, so I know he is fully booked for this month.
If you want to give him a call, it's K. H. Motors on 01773 714450 8.30 to 5 Monday to Friday. Location is five minutes from M1 J26, or 15 minutes from A38/M1 J28.
