All of the SL models are going to be heavy on fuel, despite improved claimed economy and emissions over previous generations, and depreciation will also be very costly. If you need to even ask about emissions and economy, avoid the AMG SL 63 and SL 65. Although the SL’s list price starts high, our independent research suggests that you’ll be able to haggle a fair amount off that. Mercedes will also help you out if you’re looking to finance; their PCP deals make the SL far more affordable than some rivals.
Mercedes-Benz SL quality & reliability
There’s a three-year warranty with no mileage limit, which is handy as Mercedes finished in the bottom quarter of our last reliability survey for manufacturers. If there's another chink in the SL's armour, it's that its cabin is starting to look and feel a little dated next to those of its rivals in terms of quality and infotainment. It's not surprising; this is a facelift of an older design, and the SL doesn't yet benefit from Mercedes' latest materials.
Mercedes-Benz SL safety & security
LED headlights that bend their beam around corners and switch to main beam when it’s safe to do so are standard, as is an automatic parking system and sensors. The SL also warns if it senses driver fatigue, if you’re too close to the car in front or if an imminent collision is detected. Blind spot warning and lane assist are optional on all but the SL 65. The SL hasn’t been crash tested. An alarm and immobiliser are standard, and the hard roof deters thieves better than fabric-roofed rivals.
