Thieves caused damage to the vehicle but were unsuccessful - there would have been no way to drive off with the vehicle since the car is a mock-up and has no engine.
A 1970s era Mercedes show car was the victim of an attempted theft as the car waited on a transport trailer for a Channel crossing on its way to the Mercedes-Benz World Brooklands.
The thief or thieves damaged one of the gullwing doors and the nearside front wing of the C111 trying to get into the vehicle but were unsuccessful. They likely had no idea what this car was since there would have been no way to drive off with the vehicle - the car is a mock-up and has no engine.
The C111 was a concept car by Mercedes-Benz which came in various alternative power train iterations, for which it was intended, throughout the 60s and 70s. Besides being fitted with turbocharged petrol/gasoline engines, Mercedes tried diesel and rotary engine power plants on it too. A C112 version also followed, fitted with a 6.0 liter V12. No version ever made it to production.
The car eventually made it to Mercedes-Benz World and the damage has since been repaired.
