Business and municipal operators keep on finding new uses for Mercedes's evergreen Unimog, and this time it's for use as an all-year round snowplow and emergency operations vehicle. This particular Unimog was ordered by Felsenau authorities with the optional 4-wheel steering system. With 4?wheel steering, the Unimog becomes considerably more manoeuvrable with its turning circle reduced by 30 percent. This capability became particularly useful when a recent snowstorm laid on 10 meters of snow on the mountain roads of Vorarlberg in Austria.

As this auction result shows, it's not only Ferraris that have a lock on the staggering amounts that collector cars sell for nowadays. At a recently concluded Gooding and Company auction, a 1955 Mercedes 300 SL Gullwing garnered a $4,620,000 bid that made it the top seller for that auction. In comparison, a Ferrari 250 GT LWB California Spider changed hands at the same auction for $3,905,000.

What made this Gullwing so expensive is the fact the it's practically a museum piece in terms of condition. Being one of only 29 alloy-bodied 300 SLs was also a major factor in making the car so desirable. Aside from the rarity of such a body, finding one on the open market is also  very rare occasion, so much so that the buyers who desperately wanted the car ended up in a bidding war.

And that's actually a good thing! Because if there were no tuners like RENNtech who seek to obtain the ultimate performance from cars they lay their hands on, we wouldn't be seeing this video.
