Well right now I own a 1989 525i, 5 speed and I just spent the entire weekend driving a 1990 535i, 5 speed which I have an opportunity to own. Well I never thought 40 more Horspower would be such a difference, and the torque well... Anyway I'm almost a hundred percent sure I want this car. The only concern is that there are 280000 km (175000 miles) on the car. The car is very solid, the paint is in good shape and the car has been serviced by father's garage ever since 1992, so I know the entire history. My 525i has 220000km (138000miles) and just got painted. What do you guys think?
