Thanks for the suggestion. I'll ask at my closest dealer today.
I cleared the codes. I'll see if any return.

I'd like to drive it around for a few days as the owner is still out of the country and wouldn't even know (ha-ha).

This car was owned by a family which owned a service station in a good neighborhood. 'Twas the wife's car.

The new owner is a man who has worked there a long time and claims the car got top notch maintenance.

Of course all that was done without records. The new gas jockey claims the other car they were selling (an old Benz) was in superb shape.

Tantalizing this is.
