I am planning to buy a E34 520I /1990 and would like to know if there is anything special to look out for..what are the weak points etc.. does this car have any rust-traps.??
The car is clean and looks well maintained but has quite high mileage (270 000kms) and about 3 past owners. It idles evenly and the gearchanges are smooth. On light braking I can feel the pedal pulsing slightly but its OK on hard braking. Discs?

I notice some newer models have a 24V badge on the back.. Is this a totally different engine or just a new head. The car is an auto, any major problems with swapping to a manual trans?
