The 1998 Mercedes-Benz SL-Class is part of the carmaker's fourth generation of iconic luxury roadsters, introduced in 1989. It comes with two engine options: a 3.2L inline-six producing 228 horsepower in the SL320 model, and a 5.0L V8 pushing out 315 horsepower in the SL500. Both are paired with a smooth-shifting 5-speed automatic transmission driving the rear wheels. The range-topping, high-performance SL600 features a 6.0L V12 engine that's good for 389 horsepower. This model year includes notable features such as a Bose audio system, leather upholstery, and power-adjustable seats with memory functions. Safety technology includes antilock brakes, traction control, and front airbags. The hardtop, which stows beneath a metal cover in the trunk when not in use, ensures year-round comfort.
