Porsche has been named as the least reliable car brand in the UK in a list dominated by premium manufacturers.
Data compiled by Warrantywise, analysed over 131,000 extended car warranty plans to compile a list of the least reliable makes on British roads.
Each brand was given a total score out of 100 with Porsche achieving the lowest score by a significant margin.
The German firm scored just 35.1/100, placing it well short of second-placed Land Rover which scored 40.2/100.
The highest repair costs reported on Porsche models was £10,784.60, which was actually at the cheaper end of the scale compared to some other manufacturers on the list.
The priciest repair on second-placed Land Rover came to a whopping £23,889.53, while Jaguar, which came third, had a highest repair cost of £16,990.02.
Also on the most unreliable list was Alfa Romeo (52.4/100); Audi (58.6/100); BMW (59.8/100) and Mercedes-Benz (60.4/100).
The list was completed by Vauxhall (68/100); Volvo (68.9/100) and Mitsubishi (69.4/100).
Lawrence Whittaker, CEO of Warrantywise said: ‘Premium prices really do make for premium costs, as is evident from the data in the Reliability Index.
‘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.
‘One way of ensuring that your pride and joy is safe and affordable in the long run is by purchasing a warranty, and we always strive to make sure our customers have the best possible service and product.’
