But not all SL280’s are built equal! The engine and suspension are essential factors to consider, and we recommend picking one with the V6 motor and spring & shock system, just as seen on this SL280. It’s V6 motor is refined and a better performer than the earlier and more common straight-six. It also has a finely tuned spring & shock suspension, so you don’t need to worry about those expensive ADS (adaptive damping system) bills!
