Porsche tops list of unreliable marques
Porsche has been named the most unreliable marque in a reliability index developed by Warrantywise, a UK provider of third-party used car warranties.
Joining Porsche is a range of premium luxury passenger car makers, proving that despite a high price tag, used luxury cars could also cost owners a lot of money in the long run.
Porsche was the least reliable used car marque, scoring 35.1/100 overall, with the highest repairs totalling £10,784.60.
With a larger, and the most expensive, overall repair bill totalling £23,889.53, Land Rover came in second, its Range Rover model named the least reliable model this summer. Land Rover’s UK counterpart, Jaguar, placed third from bottom, with the engine’s turbocharger proving the costliest single repair at £16,990.02.
“Premium prices really do make for premium costs, as is evident from the data in the Reliability Index,” said Lawrence Whittaker, CEO of Warrantywise. “With more technology in high-end cars than ever before, we suppose it’s only natural that they require a bit more TLC than normal. As the concept of luxury has expanded and become more available to a wider audience, high-end supercars are clearly still in high demand.”
In developing the index, Warrantywise analysed more than 131,000 extended car warranty plans.
