The R129 has always been my favorite iteration of the SL roadster. Softer and more modern than the classic R107 that it replaced, but still sufficiently angular that it doesn’t succumb to the awful jelly bean aesthetic of the late 80s and early 90s, the quintessentially Mercedes design remains attractive today; sporty and taut yet elegant and handsome. While most US buyers opted for the V8 500SL or the range topping and magnificent V12 in the 600SL, the car could also be had with an entry level 3.0 liter straight six, as found in this 300SL version. Already a relatively uncommon spec, this car features the especially rare manual gearbox, available only on six cylinder R129s.
