1972- 1989 Mercedes Benz SL Class WL 107
The W107-series SL, sometimes also known as the R107 (for Reihe, or ’series’ rather than Wagen), was nicknamed by insiders as the ’Panzerwagen’ when it was under development, because it was so heavy. At 3,400lbs, it was a good 300lbs more than the W113, and it wasn’t quite as elegant although the pagoda-style roof was retained. Upright, square headlights replaced the ovals, though US-market cars got twin circular lamps, and although it was actually only a quarter of an inch wider than the W113, it looked a lot bigger with its lowered, more squat stance and longer wheelbase.
