Since the demise of the Hummer, former Governator Arnold Schwarzenegger has moved on to the Mercedes-Benz Unimog. He was spotted on Thursday driving around the rough terrain of Santa Monica in his new monster truck.

The 65-year-old’s new enormous ride, the Mercedes-Benz UNIMOG, retails for about $250,000 and is the vehicle of choice for the army in Germany. You may remember we spotted Arnold testing the Unimog’s at the Unimog Museum in Germany back in July.

A number of fans gathered to admire Arnold’s ride – with one overzealous woman getting so excited that she climbed onto the front of the vehicle and clung onto the front of the bull bars.

The vehicle has reportedly been modified to fit the LA roads after being customised by a German company called Mertec.

The former actor purchased the Mercedes-Benz Unimog to go cruising around the Californian city, which is the army vehicle of choice for many different armies, including Germany, Britain and the United States.

According to Mercedes Benz, the Unimog range of cars is perfect for: ‘The most extreme, arduous tasks, including: fighting forest fires, performing rescue operations during catastrophes or maintaining power supply lines.’ Perfect for what the Terminator might face while he battles with his soon to be ex-wife

Arnold happily shook the hands of fans before hopping into his new pick-up truck and driving home.

Arnold Schwarzenegger has long been famous for driving Humvees, at one time owning an entire fleet of the High Mobility Multipurpose Wheeled Vehicles. But what do you do when you’re looking to diversify your collecion, what kind of car does an action star move on to? It looks like it will be a brand new Unimog U1300 for Schwarzenegger. The former Governor of California was seen testing the new Unimog on the test track at the Unimog Museum this last week.

For both the museum staff and museum visitors,Schwarzenegger’s recent visit came as a complete surprise.  To the amazement of many museum visitors, Schwarzenegger tested alongside former Mercedes-Benz employee and Mertec founder, René Dusseldorp, on the trail outside of the museum. Schwarzenegger then made his way through the current Unimog exhibits “Special Operations Unimog: Rescue – Help Mountains” result. An Austiran native from the Unimog drive system area was particularly happy about his local celebrities visit.

The Unimog Museum in Gaggenau, located in the Murg River Valley, is open Tuesday through Sunday (10am – 5pm) and offers something for the entire family.
