Older exec and luxury cars for reliability main image

Executive and luxury cars are mostly ordered new by business users. They're therefore designed to be whisper-quiet motorway cruisers with the hest of interiors, decked out with the latest technology and creature comforts. They're also generally economical. 

While the badge on the bonnet is important to new car buyers, if you're buying used, you're more likely to care about how reliable the car will be and how much it will cost you if any of those bells and whistles go wrong. That's where the Lombardyexperience? Reliability Survey can help. With data from more than 18,000 car owners across the UK, we can help you sort the good from the bad. 

Looking exclusively at the results for used cars aged four to 10 years old, we've rated all the executive and luxury cars we were told about. Those with more faults and costly repair bills get a lower score than those that provide problem-free motoring. Here, we reveal the top 10 most reliable older executive and luxury cars and the least reliable ones that are best avoided. Our data covers every variant and bodystyle of each model.

Although 31% of Superb owners reported a fault, the most common areas of concern were the bodywork and brakes, followed by the battery, fuel system and suspension.
