2008 Mercedes-Benz SL-Class Review

KBB Editors

Updated December 23, 2019

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

The 2008 Mercedes-Benz SL is more than just a performance dynamo; it’s an attention grabber. The car looks as good with the power-operated hardtop covering the cockpit as it does when the top is retracted. If you believe a car should signal to the world the level of your success, the SL is the perfect spokesperson.

Cons

The only reason not to like the 2008 Mercedes-Benz SL is the price. Don’t feel bad; well over 90 percent of the rest of us can’t afford one, either.

What's New?

Changes for 2008 are limited to new 18-inch wheels for the SL550 and the addition of Nappa Leather to the Trim Package.

In the world of premium and exotic roadsters, only a handful of vehicles offer the exclusivity, performance and overall reliability of the 2008 Mercedes-Benz SL. Highlighting its stunning exterior is a clever retractable hardtop, allowing the SL to serve as both coupe and convertible. The SL’s varied model line delivers performance ranging from impressively quick to awesomely fast, and the car’s extensive list of safety features is unsurpassed in this category. Few exotics can match the SL’s impressively smooth and comfortable ride, either. Price may be the SL’s only Achilles’ heel, with the lowest-priced SL starting tens of thousands of dollars higher than a BMW 650i or Jaguar XK.

2008 Mercedes-Benz SL-Class Pricing

2008 Mercedes-Benz SL-Class pricing starts at $12,836 for the SL-Class SL 550 Roadster 2D, which had a starting MSRP of $97,425 when new. The range-topping 2008 SL-Class SL 65 AMG Roadster 2D starts at $27,084 today, originally priced from $188,025.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2008 Mercedes-Benz SL-Class models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the Mercedes-Benz SL-Class

As you drive the 2008 Mercedes-Benz SL you’ll feel exactness in the steering wheel and brakes and in the way the car corners and copes with emergency situations. What you don’t feel is the army of computers monitoring, controlling and adjusting every facet of the SL driving experience. Mercedes-Benz has equipped the SL with Active Body Control, an innovative suspension that helps keep the car level in sharp turns. The system can also detect when a rollover is imminent, activating the pop-up rollover bar. The SL550 combines both power and price into a very desirable package. Powered by a 382-horsepower V8, the SL550 rockets from dead stops like a stone leaving a slingshot, perhaps leaving one wondering just what in the world you might do with all the power of the other even more-potent SL variants.

Interior Comfort

The SL’s cockpit is awash in leather and power features. In fact, just about everything inside the SL is automated, which means you set it once, then forget it. We should point out that some of the controls—the COMAND system, for example—are complicated and take some effort to master. As for overall comfort, you’ll be hard pressed to find a more comfortable set of seats, and the SL’s ingenious folding top design doesn’t take up the entire trunk when retracted, leaving just over seven cubic feet for luggage or shopping bags.

Exterior Styling

The 2008 Mercedes-Benz SL blends many lines from the latest Mercedes-Benz show cars into a production coupe that words alone cannot adequately describe. A long hood, short deck, massive wheels and a barely detectable retractable hardtop put the SL in a class all its own. Deeply sculpted side scoops and a protruding nose mark a revolutionary departure from the conservative styling found on the previous generation SL. Yet below the seductive skin the SL’s legendary structural and safety features remain intact.

Favorite Features

Retractable Hardtop
The SL’s retractable hardtop works flawlessly and, when in place, is as handsomely appointed inside as any Mercedes coupe.

Panorama Glass Panel Top
The optional panorama glass panel top puts a unique twist on the retractable hardtop design.

Standard Features

As standard equipment, the SL550 has dual-zone automatic air conditioning, the COMAND system, driver’s information center, illuminated keyless remote, xenon HID headlamps with wiper/washers, auto-dimming mirrors with right-hand tilt-down feature, navigation, Bose audio, frontal airbags, dual side-impact airbags, automatic pop-up roll bar, dual 12-way leather power seats, cruise control, stability program, power tilt/telescopic steering wheel, traction control, Active Body Control, a seven-speed automatic transmission and 18-inch alloy wheels.

Factory Options

Some of the SL’s more popular options include: The Trim Package (SL550) which includes Nappa leather seats and a wood shift knob; the Sport Package, which adds an AMG-inspired body kit; and the Premium package, which adds Keyless Go, ventilated seats, cornering lamps and bi-xenon headlamps. Stand-alone options include Parktronic, Distronic automatic cruise control, panorama glass panel roof with power sunshade and a power trunk closer.

Engine & Transmission

The SL550’s 5.5-liter V8 is the best choice for mere mortals, offering acceptable power at a good price, although there is something purely sumptuous about the 510-horsepower V12 of the SL600. Speed freaks, thrill seekers and millionaires will no doubt opt for the supercharged SL55 AMG or the twin-turbo SL65 AMG, both of which offer big horsepower figures but with a significant difference in low-end torque.

5.5-liter V8
