Hello everyoneI almost close a deal with an owner who going to sell his e39 523i year 2000 at about RM70K, could someone give me some advise what are the maintenance like and what should I take a note after owning it ? The current mileage is about 135,000km. I have brought the car to the BMW mechanics, and checked everything ok included diagnose using the machine, certain things like the engine mounting & gearbox mounting, wipers that needs to be changed. Thanks.
