Costly car in the world

$4.8 million - Koenigsegg CCXR Trevita
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.
