Porsche has been named the most unreliable marque according to Warrantywise data.
Joining it is a range of premium luxury passenger car makers; proving that despite a high price tag, even for a used car, luxury cars could also cost owners more in the long run.
Analysing more than 131,000 extended car warranty plans, the Reliability Index places Porsche as least reliable used car marque – scoring a mere 35.1/100 overall – with the highest repairs totalling a staggering £10,784.60.
With a larger, and the most expensive, overall repair bill totalling £23,889.53, it’s Land Rover in second place, which also saw its Range Rover model named the least reliable model this summer.
Its UK counterpart, Jaguar, places third from bottom, with the engine’s turbocharger proving the costliest single repair at £16,990.02.
Lawrence Whittaker, CEO of Warrantywise said: “Premium prices really do make for premium costs, as is evident from the data in the Reliability Index.
“And, 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.”
