Luxury cars get all the new gadgets and gizmos ahead of more affordable models, and they're usually superb long-distance cruisers that offer plenty of space to relax in their hushed interiors.  That's all well and good until something goes wrong, when all that tech can make them far pricier to put right. 

That’s where the annual What Car? Reliability Survey, conducted in association with MotorEasy, comes in. We asked nearly 25,000 readers if their cars had gone wrong in the past two years, and, if they had, how severe the fault was and how much they had to pay for repairs.

On the whole, luxury cars were one of the least reliable types of car you could buy, second only to luxury SUVs.

However, that doesn’t tell the full story, because some models motored along without giving their owners many troubles, while others were a bigger financial liability than a payday loan. Here, we’ve used that data to investigate the most and least reliable luxury cars aged up to five years old.
