How much does the Mercedes Benz SLK cost to run?

The 2.1L diesel is the most economical Mercedes Benz SLK to run, taking into account insurance, tax and fuel efficiency.

The Mercedes Benz SLK 2.1L diesel costs £145.00 a year to tax, as it sits in tax band E.

It does not far off 57 MPG on average, which means it will cost £11.00* in diesel every 100 miles driven.

In terms of fuel efficiency, it sits between the Mercedes Benz SLC 2.1L diesel and the more thirsty MINI Roadster 2.0L diesel.

The lower the insurance group, the cheaper a car should be to insure. This model is rated insurance group 42, which is lower than the BMW Z4 3.0L petrol, but higher than the BMW Z4 3.0L petrol. (If insurance cost is important to you then the Mazda MX-5 has the lowest insurance group.)

Mercedes Benz SLK: How big is the boot?

The Mercedes Benz SLK has an above average boot space (335 litres of luggage with the seats up).

This would allow one pushchair and one large bag. Alternatively you could load up with 2 large bags or 2 cabin bags instead.

The Mercedes Benz SLK convertible is the best in class, and better than its closest rival BMW Z4.

Is the Mercedes Benz SLK easy to park?

Given a typical supermarket space, the SLK is hard to park. (If you want the detail it will fill three quarters of the bay). This is the widest car in the Convertible class, and you may need to breathe in a bit when getting in and out.

When it comes to parking on the street, the SLK is one of the hardest. It has a turning circle of 11m, and a length of 4134m, giving you a relatively small 666mm gap to turn the car in and out.

If you don’t have a drive, you should look at the best in class for parallel parking instead, the Mazda MX-5.

Which Mercedes Benz SLK has the best performance?

The fastest Mercedes Benz SLK from 0-60, is the 2.1L diesel (if you’re a petrol head, it has 500 lbs/ft torque and 204 bhp). It hits 60 mph in 6.6 seconds.

The closest rival in its class is the Mazda MX-5 2.0L petrol, which will beat your Mercedes Benz SLK to 60 by 0.1 seconds. That’s a big gap in Formula 1, but not something you would notice in your commute to work.
