Dear all BMW members,I am currently thinking of buying my booss BMW 523i -1996. He is selling at 97K. the mileage is 145K so far. He is a very "jaga kereta punya orang". As I am new to BMW cars, I would like to hear the opinion of those usign the BMW 5 series (all the sifus) such as problems that the owner encounters, fuel comsuption, maintenance charges and spare partsThank you very much for the precious opinion. Maybe this could help me to decide whether to buy it or not.-Darkquest
