Fully restored classic BMW is first such delivery to a customer. It also marks the first time BMW Welt's service center was used to deliver a used car to a client.

BMW wants you to know they'll go the distance in customer service.

The Bavarian brand's BMW Classic Center has fully restored a 1972 BMW 3.0 CSi and returned it to its owner in mint condition.

The restoration took months of work to complete, including research to re-create as much of the original car as possible and the hours of manual labor to do the work. Substantial body work was done to repair damage and electrical defects had to be fixed. The interior also got a complete overhaul.

The car was also fitted with an automatic transmission from a BMW 2.8 CS at the request of the client, instead of staying with its original 4-speed manual gearbox.

The 1972 BMW 3.0 CSi was handed back to its owner on July 7 at BMW Welt. It was the first customer delivery on a restoration project for BMW Classic Center and the first time BMW Welt delivered a used car to a client at its service center there.

The cost of the restoration was not revealed.
