Today I wanted to look at a 2016 Mercedes-Benz … SL400? Yes, that is a thing. Back in 2015, Mercedes-Benz introduced the SL400 with a 329 horsepower 3.0L twin-turbo V6 paired with a the 722.9 seven-speed automatic. The whole reason for this is that the base price was $85,000, which meant it was $23,000 less than the SL550. For legacy SL buyers, that is a big deal. You still get your SL with all the toys, but save a bunch of money if you don’t ever use 430 horsepower. This was true in a lot of households as these cars are used as Sunday cruisers and rarely get full throttle. A win-win for both Mercedes and buyers as more cars were sold and buyers save a little bit of coin. Now five years later, these could be a bargain, right?
