Rolls-Royce will build you anything if you have a thick enough wallet to pay for it. Take the Sweptail, for example. It’s a one-off coupe that a customer commissioned from the ground up. Its design draws inspiration from the brand’s classic models while borrowing styling cues from the world of super-yachts. Nearly every part of this car is unique, and the project took four years from start to finish, which explains why it cost approximately $13 million.
By far the most expensive car on our list, the Maybach Exelero makes its appearance under Honorable Mentions due to its one-off status. The Maybach was also built way back in 2004, but that actually makes its sticker price more impressive.
Adjusted for inflation, the Exelero would cost around $10.1 million in the U.S. today, which is close to the GDP of a small island nation. Money and Maybach are about as closely related as peanut butter and jelly, but the two-door further justifies its cost with a 700 hp, twin-turbo V12 and luxurious amenities.
Koenigsegg makes its first appearance on our list with the CCXR Trevita, and it does so as the most expensive street-legal production car in the world. Why so much coin? With no exaggeration, the car is literally coated in diamonds … and diamonds aren’t cheap.
For the Trevita, the Swedish manufacturer developed a new exterior finish called the Koenigsegg Proprietary Diamond Weave, which involves coating carbon fibers with a diamond dust-impregnated resin. We can’t even fathom how much the touch-up paint costs.
Underneath the lustrous finish lies a 4.8-liter, dual-supercharged V8 with a total output of 1,004 horsepower and 797 pound-feet of torque, which means it should have little to no trouble overtaking semis on the freeway. The car’s specifications — in both performance and price — are nearly comical at this point, and just three were ever made.
Poison. That’s the name Lamborghini chose for the modified Aventador roadster you see above — translated from Spanish of course — built to celebrate the automaker’s 50th birthday. We can’t speak for the company’s motivations, but the name is fitting for a vehicle that looks so positively deadly, so undeniably venomous.
