OK... You don't buy a $45K BMW for 12% of what it was worth new, and not expect to have to change any parts. Like the new battery I bought yesterday. My recently purchased 2000 528i with 145k miles is still running on the original clutch. This situation is not going to last. In fact, I've noticed that the clutch is slipping now (although the car is still drivable). What should I keep in mind when clutch replacement time comes along, and what can I do now to prolong the clutch life so I can buy myself another month or so of use?
