I live in Hawaii and drive a 1994 540i. The car is "long on tooth" but it still has less than 100k on the odometer. After all, you can't drive very far on an island.
I purchased the car used back in 1998 with only 33k miles and having been doing most of the maintenance and repairs by myself. I plan to keep the car as long as it continues to provide a reliable means of transportation.
