The Mercedes Gullwing is one of the most sought-after vehicles on any auction block. In the 50s and 60s, it was a revolution; produced in very limited numbers, it was the fastest production vehicle available at the time and it was also the first to use direct fuel injection. Besides being at the pinnacle of technology, its trademark gullwing doors are what defined its legacy. This 2009 iteration of the classic 300SL retains the gullwing doors and also ups the ante with a 5.5L, 370hp AMG-sourced engine. The amazing curves of the aluminum and fiberglass body mimic the original lines of the car, and they are simply breathtaking. Side exit exhaust, removed bumpers, and AMG custom wheels are just some of the few new-school touches that make this old-school hotrod a modern classic.
