The engine on the C15D will outlast the pyramids, but the body and chassis will NOT - tinworm a speciality.

Also there are about 15,000,000 different variants for usually standard things like wheelbearings electrical relays, brake calipers, etc, etc, so maintenance requires knowledge and care with chassis numbers (and sometimes taking the old bit to a specialist repairer not necessarily a dealer.    I had a Visa Diesel, a cousin to the C15D for a while.
