We don’t think we can put it more eloquently than the folks at Coys UK, here’s how they introduced a Porsche Kremer CK5: The name Kremer is synonymous with Porsche in motor sport, in particular in endurance events such as the Le Mans 24 Hours, and during the 1970s and ’80s the Cologne-based race specialist’s modified 911, 934, 935 and 936 models enjoyed much success. With the advent of the fuel formula-regulated World Endurance Championship in 1982 for Group C cars, however, the Kremer brothers Erwin and Manfred had to build a one-off machine to bridge the gap until Porsche made its latest 956 model available to privateer teams.

This one is currently located in Australia, asking $299,000.

Here’s a video from 1982 Brands Hatch 1000km when these cars ran professionally. Some say this era was the pinnacle of motorsports, look for some great racing from the short lived Porsche 936, the spectacular Porsche 956, Lancia’s, Sauber’s, Fords and one of these three Kremer CK5′s running past at least a couple times:

The Kremer CK5′s were built off ‘replica’ Porsche 936 chassis. The Kremer brothers designed their own body, unfortunately not as sleek or commanding looking as Porsche’s new-at-the-time 956. This particular car seems to have a solid history with some decent drivers, more pics and info here. Importantly, the seller claims he’s got the original Wagenpass and sale letter from Kremer.

Like most anything that’s 1 of 3, this one is hard to put a number on. The Coys car sold for less money 3 years ago but that doesn’t mean much. With the growing popularity of historic racing, Group C prices are surely on the rise. For more info see the original ad here.
