I pay £55 for my independent MOTs and my service guy takes it there and gets it passed, tweaking whatever might need doing at the time ....... we have two cars, they always pass ........... MOTs go with the annual servicing and I pay him £30 an hour ( no vat, low turnover ) and cost price for parts he uses.
Been successfully looking after my cars now for 6 years ......... bills are usually on the floor and he's competent, diligent and all the things one wishes in a mechanic.
