8. Porsche
Porsche cars are generally well built and very reliable which makes maintaining and repairing them easy. Parts for Porsche cars are relatively expensive, and the engine, for example, uses more oil than the average engines of the same size. That is one of the reasons people would rather choose some other brand if looking for some cheapest luxury cars to maintain, but according to some Porsche owners, owning a one is not as expensive as it sounds.
