The guy I bought my first 300TD from didn't know much about the maintenance history at all. Some folks just use cars, some (like us) - are more involved emotionally with our MB's.

The good news is, for your car, it will be getting regulair valbe adjustments. After that first one get's done, you'll surely hear and feel a big difference (if it hasn't been worked on in years).

If I could have picked a color for my W123, it would be like yours.
