Neg. Full books at a reputable shop I know of. Just had 6k cyl head rebuild, front lip spoiler repaired and reinforced 1.5k and many other bits and bobs.. We're E39 people... I've had 2, mum 1, mum's ex 2, dad 1. All been awesome and reliable with reg servicing.
Also helps when your mechanic knows these cars better than anyone else...
