I have had no issues witb mine at 53k so far but i wont knock on wood. My E class had lots of nickela nd dime issues. Buddy had a new e350 thats been in for repairs more than its been in his garage lol. Luckily its all warrany work. German and reliability are almost oxymorons though. I sold bmw for several years and while they are great performers they are about as relieble as a Yugo.
