Thanks juergen, i will have a look tomorrow if i have time. I think that my car has more then one issue so hopefully it is something relatively simple to at least get some power and speed back, fingers crossed!
i think you hoping it's got something simple now wrong with it - if he's just replaced your knackered pistons with 4 used ones (and done nothing else) there's a good chance he's wasted his time and your money
ask for the bill and make sure it's itemised - it should include new rings and a hone at the very least
......... who else has work done on their vehicle without first agreeing the price ?
