2017 Mercedes-Benz C 2.1L Diesel · KJ17 TKC

The 2.1-litre diesel engine in the C-Class typically returns around 55-65 mpg in real-world driving, making it economical for a car of this size, though fuel economy will degrade if the DPF becomes clogged. Road tax for a vehicle of this age and emissions bracket typically falls into a reasonable band, but you should verify the exact VED cost using the registration document. Insurance for a Mercedes-Benz C-Class diesel generally sits in the higher insurance groups, so obtain quotes before purchase. Based on fuel, tax, insurance, and typical maintenance for a premium German saloon of this age, estimated annual running costs fall in the region of £1,200-£1,500.

Although the MOT history shows no recorded defects, the aggregate model data indicates that suspension arms, tyres, and headlamps are the most common failure points on the Mercedes-Benz C-Class, so these areas warrant close physical inspection regardless of the clean MOT paper trail. Examine the front suspension components for wear, as suspension arms are the top reported failure reason across 419,691 analysed examples of this model. Check all tyres for even wear and adequate tread depth, as tyres are the second most common MOT failure point on this model, and uneven wear can indicate alignment or suspension issues. Finally, inspect the headlamps for clouding, cracks, or condensation, as headlamp defects are the third most common MOT failure on this model, and replacement units from Mercedes can be costly.
