8. Bentley Mulsanne
Bentleys are understated when compared to other ultra-luxury vehicles, but they do not skimp when it comes to luxury features. You’ll have to make extremely good money not only to afford the purchase price and repairs for a Mulsanne, but to also afford the payment on your gas card each month. Like the Aventador, the Bentley Mulsanne achieves just 11 mpg in the city and 18 mpg on the highway. At least the interior is incredibly luxurious, but those massaging seats, wood trim and integrated iPads all add enough weight to keep you returning to the gas station every few days.
