Many congrats to Herman and its happy owner... This is one hell of a car, the W123, maybe the most reliable and well-built car of all time.
I remember reading the ADAC (German car association) report of reliability from the time of the W123. The 8 first places in the report were...the 8 motorizations of the W123.

Just priceless isn't it?
Another amazing detail: a W123 200D has to travel more than 850.000km (yes, 850.000kms) before it experiences its first problem (other than a puncture of course)!! That's what I call indestructible...
Many happy kms with Herman!
