The Mercedes SL-Class Fifth Generation Restyling is a two-seat Roadster built for open-air touring. You get a grand-tourer layout rather than a compact daily runabout.
You match a Mercedes SL-Class engine to how you drive rather than assuming one default. The 3.5 AT Roadster is one example: gasoline, automatic, and rear-wheel drive, so you skip clutch work and the drivetrain sends power to the rear wheels. Other powertrain choices exist beyond that configuration.
