2019 Mercedes-Benz SLC 2.0L Petrol · 14 J

Fuel economy for the 2.0-litre SLC petrol is typically in the mid-30s mpg in real-world mixed driving, dropping into the high 20s during enthusiastic use — budget around £1,400-£1,800 per year in fuel assuming modest 5,000-mile annual use. Road tax sits in a relatively low bracket thanks to Euro 6 compliance, though the SLC's CO2 figure of around 150 g/km places it above the £40 VED threshold, so an annual charge applies. Insurance tends to sit in the higher groups for a premium two-seat convertible, so obtain quotes before purchase. Servicing through Mercedes-Benz specialists tends to be moderately priced for a 2.0-litre petrol, but expect higher costs for roof mechanism servicing, brake work, and any transmission attention. Estimated annual running cost: £1,800-£2,400 covering fuel, tax, insurance, and routine maintenance.

Although the MOT record is clean with no advisories or failures, a thorough physical inspection should still cover the items most likely to affect a used roadster. Inspect the retractable hard-top thoroughly: listen for unusual noises, watch for hesitation during operation, and check that the boot divider and luggage area reset correctly after the roof is stowed. Examine the underbody, suspension arms, and brake discs for corrosion — a 2019 car spending long periods idle (as suggested by the low mileage) can develop surface rust on brake discs and undertray components. Check the condition of the tyres, as low-mileage cars often suffer sidewall cracking and uneven age-related wear rather than tread wear. Inspect the interior electronics, including the infotainment system, COMAND controller, and convertible roof warning indicators, as these are not covered in MOT testing but are common weak points on Mercedes models of this era. Finally, verify there are no warning lights illuminated on the dashboard and request a diagnostic scan, as the MOT will not reveal pending electronic faults.
