Engine mounting, valve stem seals.
A very solid strong car with great cruising performance and reliability.
Still gets looks and very classy car.
I've read some of this reviews and consider buying this car, but I have only one concern: Where do you get parts for such an old car? They must cost fortune?...
Sorry to be so late answering your comment-
You can buy parts almost anywhere- MB supplies parts for any vehicle they ever made- probably pretty expensive for SSK 500 but W114s are no problem and NOT expensive.
