One of the greatest crimes in automotive history were the 5 mph bumpers mandated by the National Highway Traffic Safety Administration in 1973. As a result, our favorite cars from Europe went from being great designs to cars with massive underbites. Arguably no car was hit harder by this mandate than the Mercedes-Benz R107. A great, boxy design was totally transformed because of these massive bumpers. Thanks to another ridiculous rule at the time that required sealed beam headlights, the R107 design was basically decimated. Thankfully, there are enthusiasts out there who told the NHTSA where to go and swapped back on the slim bumpers and non-sealed beam headlights. This 1986 560SL up bid in California is one of them. Thank goodness.
