The Warrantywise Reliability Index, compiled on the basis of 131,000 extended car warranties, ranks the most breakable models in the UK.

It is made by Warrantywise, the Island's largest provider of extended warranties. It is clear from it that Land Rover, BMW and Porsche share seven positions in the Top 10 in terms of unreliability. You might want to keep that in mind when looking around the aftermarket for something German.

The data only includes cars up to 10 years old. As the most fragile and unreliable, the Range Rover of the previous generation is indicated. The reasons for this are frequent and expensive repairs. The insurer awarded the luxury SUV a score of 20.2 out of a possible 100, with the most expensive repair costing £23,890.

The problem for the reputation of the brand also comes from the fact that the third position in this ranking is taken by Range Rover Sport (23.1 points, most expensive repair £22,358).

The Reliability Index, based on precise and quantitative data, also ranks BMW among the most problematic models. The second position is for the BMW M3, the fifth here is the X6, and the tenth position is for the M5. About 10-11,000 lira is the most expensive repair for all three models. The remaining problematic ones here are Porsche Panamera (#4), Porsche Cayenne (#6), Audi Q7 (#7), Bentley Continental GT (#8), Mazda CX-5 (#9). Interestingly, the most expensive Bentley repair was only £6,227.
