Looking for information on a used Mercedes SL320?

Are you interested in getting a used sports car? The Mercedes SL320 is a solid choice. AutoUncle present 42 options sourced from different dealership websites and online marketplaces.

What is the price of a used Mercedes SL320?

The pricing range for a used Mercedes SL320 model at AutoUncle will start at £3,995 and go up to £24,948.

The price for the German car varies according to five main factors: the year of manufacturing, engine capacity and power, the car's fuel economy, how far the car has already travelled and the level of equipment in the car.

For example, a newer model with fewer miles recorded, or a more luxurious variant with a powerful engine, typically commands a higher price than a car from an older model year, with higher mileage and no optional extras.

What versions of the Mercedes SL320 are available based on equipment?

When assessing the price tags of second-hand Mercedes SL320 cars, it is important that you only compare with the deals of cars with a similar engine and trim level. Otherwise, you could reach a wrong conclusion on which car to purchase.

Which fuel types does the Mercedes SL320 come with?

Petrol is the foremost fuel option for the Mercedes SL320.

We strongly advise considering your driving habits prior to choosing among the various fuel types. How many miles do you typically drive each week? Are your drives mostly short trips, or do you tend to embark on longer routes?

If you drive mostly short distances, range is not crucial - so electric, plug-in or petrol are obvious choices. For daily long journeys, electric cars make the most sense if you can charge easily. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. Despite the rise of electric cars, diesel can still be useful for long journeys and lack of charging options. Keep in mind that diesel engines with high emissions have been banned from entering cities in a range of countries.

In which body styles can you buy the Mercedes SL320?

The Mercedes SL320 only comes in the cabriolet body type in the UK. A cabrio or a convertible is a fantastic way to give the driving experience a new dimension. These days, most cabrio models have excellent hoods and weather gear, making them suitable for driving year-round. It’s worth noting that convertibles tend to be heavier than normal cars due to the lack of roof, as thickener is applied underneath the car to strengthen the chassis.
