Basically, the car was pranged around the front wing - they obviously thought I didn't want it back and must have fiddled with it as there were a few bolts missing from the gearbox and it looks like they put a new clutch in but didn't adjust the cable right.
So anyway, I got the car back, sorted the bodywork and replaced the clutch but basically, it didn't need replacing (just adjusting) as it was a brand new one in there anyway - so if anyone wants a brand new micra 1.3 clutch, do let me know.
