I am the original owner of a 1982 and 1987 528E BMW. I have over 168,000 miles on the 1982 which is located in Florida and is only driven 8 months out of the year and is in very good shape. The 1987 is located in Michigan and is driven 4 months out of the year and has over 240,000 miles. Recently, I discovered that one of the keys to maintaining both cars in running shape is to make sure that the ECU is functioning well. The 1987 has had the fly wheel replaced twice and the 1982 has had a transmission overall.
