Ownership cost

What used Mercedes SL-Class sports will I get for my budget?

Remarkably, you can buy this once £70,000+ car for around £20,000, and because these are often "high days and holidays" cars, even early 2012 examples won't have huge mileages. Most will be the smaller engine SL 350, with the less popular SL 500 carrying a premium and most examples sitting at around the £25,000 mark. A facelifted 2016 SL starts from £30,000 for an SL 400 with the revised engine. Expect to pay nearer to £35,000 for a pre-facelift SL 63, and more like £60,000 or more for the post-facelift version. 

A year-old example with minimal mileage form a Mercedes dealer can be found a little less than £50,000, which is a useful saving over what one cost new.

How much does it cost to run a Mercedes SL-Class sports?

MPG

Sticking with the base engines means you should have to stop less for fuel. The most economical is the SL 350, with a combined figure of 37.7mpg, followed by the SL 400 at 36.7mpg. Then there's the SL 500 at 30.7mpg, but the SL 63 and SL 65 are by far the worst at 28.5mpg and 24.4mpg, respectively. These two most definitely needed to have been ordered with the enlarged 75-litre fuel tank.

CO2 emissions

The SL certainly isn't going to win any climate change awards because even the best engine (SL 350) emits 176g/km, with the SL 400 upping that marginally to 178g/km. Go for either of the two V8s and that figure gets bumped up to 214g/km for the SL 500 and 234g/km for the SL 63. Both pale in comparison to V12 SL 65 with an output of 270g/km.

Road tax

Road tax for all models registered before 1 April 2017 will vary depending upon the emissions the engine produces (see paragraph above for more information) while examples registered after this date will render owners liable to pay a flat rate fee, plus and additional fee because every version of the SL cost more than £40,000 when new. Fortunately, this yearly additional fee only lasts between the second and sixth years of the vehicle's age, then it goes back to the flat rate fee.

Servicing costs

Looking after you SL at a main dealer will not be cheap because even opting for fixed-price servicing will see you forking out over a £1000 for pre-booking the following two services.
