A brief history lesson before we get on..
Back in 1967 a company that would change the fate of Mercedes-Benz forever has seen the light for the first time. The former Daimler-Benz engineers Hans Werner Aufrecht and Erhard Melcher, have donated the first letter of their surnames ,followed by a “G” for Grossaspach – Aufrecht’s hometown; marking the emergence of AMG as we know it today.
The company's mission was to modify engines and sell parts that clients could use to upgrade their Mercedes-Benz cars, and that was the case for a few decades until Mercedes have decided to recognize AMG’s efforts and there was a co-operation agreement signed between the two in 1990.
The first joint product between AMG and Mercedes-Benz, the AMG C36 would not be introduced until 1993. For years prior to that, the two companies were cooperating to the extent that the AMG cars were being delivered with full company warranties through Mercedes-Benz dealers, however these vehicles were prohibitively expensive and therefore very rare.
The Mercedes-Benz 560 SEC AMG 6.0 was one of these few models produced in that era, AMG planned to produce at least 100 of these, but the final production number ended up being around 50 units, with each costing around $200,000. That's in 1990 dollars.
Rather than just attaching a cold-air intake and a performance exhaust, the engineers at AMG swung for the fences when developing their version of the 560 SEC. The V8 engine was completely rebuilt with newly designed AMG heads featuring DOHC per bank and 32 valves, capacity was expanded from 5.6 litres to 6 litres. This modified V8 produced twice the torque at half the engine speed of the original 5.6 litre Mercedes-Benz engine.
With a timeless design and such a high-end performance it is diffidently a car for the keeps, I've been always fascinated by the designs of the 80s and early 90s but this one stood out for me; along with the fact of rarity it is incredibly difficult to look for one. However I stumbled across a few here and there and found that two models were sold on RM Sothbey's. A 1990 model featured on the top of this article for €149,500 in April this year, and another 1989 model for €297,500 back in 2015.
