Hello,

I just bought a '97 S500 Coupe with 100k miles, all services have been done and the next due is at 105,000 miles. Should I be thinking about a timing chain and tensioner? Any other mileage related things that should be done that the service schedule hasn't hit yet?

I'm taking the car from a warm climate (AZ) to Wisconsin and was going to change the car over to synthetic if it hasn't been already. Should I use the 0w40 like my ML uses?

I really thank you for your help and responses.

Matthew
