I plan to buy a 530 japan spec 03 model and was quoted rm288k for it. Any idea how much problems I will be facing if i proceed to buy this unit? How abt the engine, is it also old model engine compared to the perhap 2005 onward model? I call ab and ask if they would service rekon unit n the reply was a yes but have to register the unit with hq 1st. I also heard that BMW's car wont want to start if i fail to do the regular servicing at the the specific interval,is this true?
