Try to avoid BMW above 5 years old, i learnt my lesson, my E60 repairs alone cost me more than RM35k stretch of 4 years ownership (Not including routine servicing.) I thought i got a lemon but did some survey among friends who owned E60 preLCI or LCI gave pretty much the same problems.

Local unit, Opal got lotsa bad reviews if u google it, one case i read they claimed that part needs to send back to UK to service but owner have to pay the postage fee
