Overview

The 2014 Mercedes-Benz SLK-Class Convertible is a compact convertible offered in 2 trims, starting off at a base MSRP of $43,525. For that price, it mainly competes with the Porsche Boxster Convertible, the Audi TT Roadster, and the BMW Z4 Convertible. Between 2 trims, the Mercedes-Benz SLK-Class offers 2 powertrains. The base engine is a 1.8L turbocharged Inline-4 capable of making 201 horsepower and 229 lb-ft of torque. If more power is required, there is also a 302 horsepower-making 3.5L V6 engine. The inline-4 engine is mated to a 6-speed manual transmission while the V6 engine is connected to a 7-speed automatic transmission as standard. The SLK-Class reaches 60 mph from zero in 6.8 seconds on its base engine, which gets pumped up to 5.6 seconds with the 3.5L V6. Depending on the powertrain, the SLK-Class can manage a combined fuel economy between 24 and 26 mpg. While we're on the topic of choices, the 17 striking colors the SLK-Class comes in really pull you towards itself.

Buying Advice

It's best to skip the base trim because it's underpowered. Upgrade to SLK 350 trim, which includes everything in the Premium 1 package, plus the Lightning package, which adds adaptive bi-xenon headlights.
