Are you interested in buying a used sports car? Look no further than the Mercedes SL350 - an excellent choice! AutoUncle has 140 used Mercedes SL350s for sale in the UK sourced from different dealership websites and online marketplaces.
The pricing range for a used Mercedes SL350 model at AutoUncle will start at £3,995 and go up to £19,995.
The German car is being offered at different prices based on mainly five factors: manufacturing year, engine size and performance, fuel economy of the car, vehicle mileage and the trim level of the car.
For instance, a more recent model with limited mileage, or a premium variant featuring a powerful engine, typically commands a higher price than an earlier version with less equipment and higher mileage.
Here is an overview of the most popular equipment variants for Mercedes SL350, sorted by number of cars for sale and their market price:
When reviewing the price points of used Mercedes SL350 cars, it is important that you exclusively compare with the offers of cars with the same engine and equipment variant. Otherwise, you might make a wrong conclusion on which car to acquire.
The primary energy source for the Mercedes SL350 is petrol.
Before you finalize your choice of fuel type, we suggest thoroughly evaluating your driving habits. On average, how many miles do you travel in a week? Do you frequently make short journeys or are your trips generally long?
If you mostly drive short trips, electric cars, plug-in hybrids or petrol cars may be relevant. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. For very long daily driving without charging options, a diesel car can still be relevant. Be aware that in several countries, diesel engines that emit high levels of pollutants are barred from urban areas.
On AutoUncle, the Mercedes SL350 is exclusively offered in the cabriolet body style. Cabrios and convertibles elevate the driving experience, offering an open-air thrill. Nowadays, many cabrios are suitable for year-round driving due to their high-quality hoods and weatherproofing. However, it's worth noting that convertibles tend to be heavier than standard cars. The absence of a roof often necessitates additional reinforcement to the undercarriage to bolster the chassis.
Several vehicles that are similar to the Mercedes SL350 are available.
