2018 Mercedes-Benz A-Class 1.3L Petrol · 100 AD

The 1,332cc petrol A-Class typically returns around 45–50 mpg in real-world driving, making it reasonably economical for a premium-badged hatchback. It falls into a relatively low road tax bracket due to its modest engine size and Euro 6 emissions compliance, though exact VED depends on the list price when new. Insurance sits in a moderate group for the A180, though premiums vary significantly by driver profile. Routine servicing through Mercedes main dealers is pricier than for mainstream brands, but independent specialists familiar with the marque can reduce costs considerably. Estimated annual running costs are in the region of £1,400–£1,700, covering fuel, tax, insurance and scheduled maintenance.

Given the clean MOT history, focus on areas the test does not fully cover. The 1.3-litre petrol engine in the W177 A-Class is known to have occasional issues with the auxiliary belt and tensioner, so listen for any chirping noises on start-up. Inspect the underside for corrosion, particularly around the rear axle and exhaust mounting points, as road salt exposure is common in UK winters. Check the dual-clutch automatic gearbox (if fitted) for smooth changes at low speed, as DCT units can develop juddering. The brake discs and pads should be examined for wear, as the model’s aggregate MOT data lists brake discs as a common failure point across the range. Finally, test all electrical features including the MBUX infotainment system, climate control and parking sensors, as software and sensor issues have been reported on early W177 examples.
