If the $85,000 base price of a 2015 Mercedes-Benz SL400 doesn’t scare you off, you’ll love the power, cutting- edge technology, impeccable craftsmanship and prestige of owning one of the most iconic Mercedes-Benz 2-seaters ever built. What else do you need?
As beautiful and prestigious as the Mercedes-Benz SL-Class is, you’ll get more performance out of a Porsche 911 or the new Jaguar F-Type. Neither can match the raw horsepower of the SL65 AMG and its V12 engine, but they’re much better driver’s cars overall.
