Just booked my car in at a small tuning specialist for an oil service + anything else that needs doing (tracking/balancing). Cost for oil service = £36, wheel balancing £9 and full 4 wheel tracking £25. Full service depends on what plugs are being used, cost of air filter etc.
The bloke I now use is a one man band, has a lot of equipment and enjoys his work (did a thorough job of my old e30, pointed out other bits and peices to keep an eye on, not just the bits that needed doing at the time).
The last garage I used emplyed jobsworths who didnt even do some of the jobs I asked them to do (but still charged for 'em).
Will let you know how I get on (is getting done tommorrow)
