I never really understood why people placed such a premium on the 280SL, over the 230SL and 250SL. It's not as though there was a dramatic increase in power or an improvement in esthetics. In fact, I'd argue that the 230SL looks better than the more cluttered look of the 280SL, (bumper guards, side reflectors/lights, head rests). Yes, there were improvements as the W113 evolved, but personally, I do like the early SL's. I find the 4-speeds great, fun driving cars.
