• Mitsubishi Lancer is the most reliable car of the last 15 years
• Audi RS6 comes bottom of the list
• Cars from Japan and the Far-East dominate

The Mitsubishi Lancer has been named as the UK’s most reliable car of the last 15 years by aftermarket warranty company, Warranty Direct. The company uses a unique system called the Reliability Index to rate individual car’s reliability.

The Lancer topped the list, with cars from Japan and the Far-East dominating proceedings. Only the Vauxhall Agila (2000-2008 model), Volvo S40 (1996-2004 model) and Mercedes E-Class (2006-2009 model) represented Europe in the top ten.

The Mitsubishi had an astonishingly reliable record, with only one in ten breaking down in any given 12 month period. Two thirds of these break downs could be put down to axle and suspension faults. The Vauxhall Agila achieved second place, with the Suzuki Alto coming in third.

Toyota and Honda fared the best in the top ten, with two cars apiece – the HR-V and Jazz for Honda and the Yaris and Aygo for Toyota. Mazda also fared well, with its MX-5 roadster placing in seventh and 11th place (one being the current model and the 11th place being the previous generation model).

At the other end of the scale, larger, more complicated premium cars dominate the top ten of the least reliable cars of the last 15 years. The 2002 Audi RS6 tops the list, with the last-generation BMW M5 coming second. These cars, with their complicated electronics and high repair costs mean that their placing is somewhat inflated.

A surprise inclusion in this top ten is the 996 generation Porsche 911, coming eighth. Again, the extremely high repair cost (an average of £847) means that whilst the car is not inherently unreliable, it is costly to repair, thus inflating its rating.

Three Mercedes, the 2002 SL, the 1996-2004 V-Class and the 2000-2007 CL  feature in the bottom 10, showing up a period of poor Mercedes build quality.
