It's a beautiful car. I have a weak spot for it--I just totalled my 1997 528 a month and a half ago. It was a wonderful car; I have very few complaints. I have some suggestions for you, though. Replace the radiator fluid and the coolant expansion tank immediately, with the thermostat, water pump, and thermostat housing close to follow. These are cheap repairs that will save you huge headaches later. If you can, have them change the coolant expansion tank for one from a 540.
The reasons for these suggestions: the coolant expansion tank has especially small holes that tend to clog easily, which will cause the 528 to overheat inexplicably in heavy traffic. You don't know how long it's been since the radiator was flushed--actually, radiator hoses might not be a bad idea either. The water pumps on the 528 are made with a plastic water impeller that will without warning fail for no reason, and cause your car to overheat badly, perhaps blowing a head gasket or worse. Upgrade to one with a metal impeller. Thermostats on those cars don't last as long as they should, and are housed in a plastic housing which is easily crushed. Replace the thermostat and upgrade to a metal (aluminum) housing. All of these parts are available online for cheap, and you can replace them all yourself if you have decent mechanical skills. An independent BMW mechanic shouldn't charge that much for installing that kind of stuff either.
Just my two cents, learned from experience with my own dear departed 528.
