The sticker price, high repair costs and what is under the hood can result in a sky-high premium. The 2019 BMW M760i xDrive, No. 5 on our most expensive list, is a good example. “It's little wonder that the M760i xDrive costs a bundle to insure, it's a small fortune to buy in the first place. The ultra-luxury sedan's six-figure price offers amenities like hot-stone massaging seats, retractable footrests and fragrance-enhanced ventilation — plus a 601-hp, twin-turbocharged V-12 that took just 3.5 seconds to scorch 60 mph,” says Mays.
