The E34 is a fairly basic car (at least by todays standards). There are plenty of parts on the market for it so finding upgraded OE replacement parts won't really be an issue. I would look at things like the serpentine belt, water pump, radiator, and definitely make sure that all the fluids are in good order. I try to change my oil every 3,000 miles with 5W30 syntheitc, change my transmission and diff fluid every 25-30,000 miles (or every 2 years), coolant every 2 years, and I absolutely make sure that my brake fluid is flushed every two years. As long as the motor has been compression checked and everything is looking good then IMO you really don't have to worry about too much.I will def. check it out. I think it needs struts to. I really want to lower it a little bit to make it look more agressive. What is the best way to go about doing that since i need new struts anyway?
