2003-2008 Mercedes-Benz SL-Class: Road Test

Although the SL500 isn't as fast off the line as might be expected, it gathers speed quickly and shows true authority above 40 mph. Mercedes' 6.1-second claim for 0-60-mph acceleration seemed a trifle optimistic; our testers managed 6.5 seconds. With a claimed 4.5-second time, the SL55 was the fastest Mercedes yet. Until the SL65 arrived, that is, with a 4.2-second claim. The SL600 is strong both from a standstill and for highway passing. A test SL500 averaged 19.5 mpg in mostly highway driving, so expect less overall. Premium fuel is required. SL-Class models deliver a fine blend of firm control and astute bump absorption, though they're more jarring than expected on really rough pavement. Even top-down, the impressively solid SL holds quivers to a minimum. Handling is nowhere near Porsche-nimble, yet the SL offers fine balance in turns with natural steering feel and good grip. Impressive high-speed stability rounds out the picture; 75 mph feels more like 40 mph. Stopping power is strong, but brake-by-wire furnishes inconsistent deceleration at around-town speeds. The brake pedal has slightly numb feel and, in simulated panic stops, excessive initial travel--but shorter-than-average stopping distances. Top-up, the SL is as quiet as most any luxury coupe, with little wind noise and almost no tire roar. Top-down, wind rush is well managed at highway speeds. The V8's rich purr is evident only during rapid acceleration. Engines are hushed at idle, and little louder at full throttle. Many buttons and switches dot the sporty, sophisticated dashboard, though all are easy to reach. Some testers have complained that pronounced coves failed to shield the speedometer and tachometer from daytime glare. The navigation system incorporates some audio and climate functions, and most adjustments require multiple inputs. Pop-out cupholders obscure the navigation screen and nearby conventional climate controls. The hardtop powers in and out of the trunk area in 16 seconds. High-grade materials and world-class finish are appropriate for this price level, but that's not true of the flimsy sunvisors and some plastic cabin trim. Stretch-out space is hard to fault on supportive and comfortable seats, though the low-slung body and long doors mean less-than-ideal entry/exit. Trunk space totals 10.2 cubic feet with the roof raised, 7.3 when it's lowered--enough for two small golf bags. The stowed top pivots for access to items in the trunk bottom. Cabin storage includes large map pockets and covered bins behind seats.

Value for the Money
Intriguingly engineered, the current SLs are solidly built, impeccably finished, and a pleasure to drive. Their style and cachet should stay fresh for years, boosting long-term resale values and taking some sting out of the startling new-car sticker prices. Of course, that's not good news for used-car shoppers, who can expect to plenty for a secondhand SL.
