Is this right,

One in yard going cheap!

It was on 4 post ramp in neutral running and rear wheels spinning but you could stop by putting pressure on one wheel with your foot.

Few little issues but are these a money pit?[/list]

Sounds like a typical diff operating as they do, but there must be a lot of gearbox drag for it to be turning the diff if it's in neutral; cold gearbox oil maybe?

Check the rear subframe mounts/floorpan, as they are reknowned for cracking.

Defo check the subframe mounts as they defo crack as Speedtouch says. I had a e46 m3 vert but had no probs with it, but it was a 53 plate with low miles. Sold it last year with 50k on it.

Also check where the pipes join the back box. The couplings crack and it's a new centre section or fabrication job

Very normal for wheels to spin in neutral if jacked up, it's just the thickness of the oil transferring movement from the input shaft.
cheers,
