So, got the car back, they didn't have the time to do /everything/ but there's some progress...
+ MOT
+ Diff has been re-welded. He drilled holes, spot welded THEN seam welded over it, and under it as well, then primed the welded area to protect them. It looks like a very nice job too, I'll take pics tomorrow.
+ New engine mounts (I had them), the old ones were *dead*
+ New control arm bushes (I had them)
+ New Inlet cam sensor -- I was planning to do that job but they did it anyway
+ New bonnet cable + 2 new catches
+ Also rerouted the overflow pipe from over the air box to the side, as the Z3M.
That last bit was nice, as the guy said he likes some fabrication work and only changed me 1/2h to do it.
What they *didn't* do is:
+ Change the transmission shaff big rubber coupling -- he said it looked in perfect condition, so it'd be a waste of money
+ Transmission oil change -- lack of time
+ Check/change the water pump/thermostat -- also lack of time.
It was not a cheap job overall, at £700 -- but just that new diff welding was probably worth it. Inlet cam sensor was also quite expensive at £95 ex vat...
Drove the car, it's a lot smoother. I still have a bit of a clunky gear changes (Typically 1st->2nd), but it seems a lot less so; Engine purrs and seems a lot smoother, likely to due to the new sensor. Will do a proper test drive tomorrow on 'known' roads...
