Our cars get most things repaired/serviced at Neil's garage in Ossy, its very handy and a lot cheaper than other places. The work is fully guaranteed and usually completed to a higher standard than most back street garages.
The only other place I have used except for MOT's and wheel alignment/tyres is
Diesel Bobs in Ribchester. If its a diesel problem Rob is your man. That was 4 or more years ago for an injection pump rebuild. I have recommended him to others who have also been impressed by his standard of work. The last one had a diesel BMW that BMW was not sure what was wrong with it. Rob sorted him out without a problem.
Oops just remembered I had a gearbox fitted a few years ago because I had no access to a ramp and another 16 years ago down south because I did not think it would make it home to change myself.
