The great thing about time is that it never stops moving. Few automakers know that quite as well as Mercedes-Benz – a company that has seen the automotive world evolve for 75 years. To celebrate that momentous anniversary the company rustled up three generations of race car haulers and put them on display. While the original 1936 Lo 2750 is cool as can be, the 1955 Blue Wonder has to be the ultimate track hauler. The truck was built from parts on hand and gets its power from a 3.0-liter straight six from a Gullwing. Too cool. Check the gallery for more photos. [Source: MB]
