My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.

Renault Clio

The Clio punches above its weight with chic French styling and a surprisingly grown-up cabin that makes city driving feel effortlessly stylish. It's an easy-to-live-with choice that keeps ownership simple and even manages to put a grin on your face when the traffic gets dull.

Having owned a clio now for the last 8 years we have found the 0.9ltr engine to work well both around town and on motorways . Averaging around 45mpg on mixed driving. The 3 cylinder engine has no cambelt to worry about . Interior has worked and worn well . No defects at all during owner ship BUT the striking red paintwork (metallic) is showing deterioration and is expensive to put right and this would be the only reason for dropping a star off the rating . There are two main services on the car an A and a B service. All they do on the A service is change the cabin filter and do the usual safety checks which costa around £120 the second B service is oil and filter change around £230 but at 36000 miles need air filter and brake fluid change which can add another £120
