Hi all Beemers,I am Zack from KL. I am planning to get an E39 525 (coz I heard that's the best) year 2000 and above with double vanos.This is my first time with 5 series. Have had an E46 2002 318i in the UK when I was working there.May I know what to look for? FYI I have looked at a couple of cars both were 520i and 523i with 2.0 and 2.5cc respectively.The yr 2000/05 523i i looked was the best with 152k KMs UK specSeems honest and original.Everything looks ok except for these :1)It came with only 1 remote key and may I know how much an orginal BMW key should have? My previous E46 came 2 remote keys, 1 service key (no remote and cant open the glovebox) and 1 valet plastic key. Should E39 be the same?2) The engine wasn't that smooth. Seems to be running on 5 cylinders if I can say it that way. The dealer wasn't so sure as he is not a BMW expert. 3) And my other prefs that it didnt have is the dealer said the owner has lost the manual booklet and service history. I am a lil anal abt it so I tried to push the price down.4) The radio display (BMW professional) was missing some pixels at the clock so i can only half of digit 2.5) It came with power rear blinds and electric memory seat but the passenger wing mirror didnt dip when I put reverse,I think it should do that right?6) rear right passenger windows doesn't work. Perhaps just the motor?Any comments on the above concerns? Should I be worried. After I tested him with my price, seemed he was willing to let go at RM50k-ish I think but I wasn't prepared to commit Any particular attention I should look for apart from normal periodic maintenance?Any advice kindly appreciated. Thanks
