I've just got back from taking it elsewhere - both camber and toe were out at the rear, with toe being miles out apparently.
It looks like the first guy was just getting it wrong. It's surprising as he comes well recommended and is a Hunter machine - and even the guy I've been to today says that the first guy is somewhere he seends work here can't fit in and has sent friends to him in the past. Weird!
Oh well, should be sorted now! Looking forward to not replacing my rear tyres again in six months, haha.
