Mercedes G63 AMG
Conceived as a military vehicle, the G-Class went a long way from a bare-bones off-road vehicle to a luxury SUV with 577 HP and 4.0-liter twin-turbo V8. The proof of evolution is still its boxy design, rugged mechanics, and stance, but everything else is modern and luxurious (via Mercedes Benz USA).
With a price of almost $200,000, this is one of the most exclusive Mercedes products, and despite its 5000 lb. weight, it is one of the fastest. At least amongst the SUV models. The G63 AMG is capable of jumping to 60 mph in 4.5 seconds. Not bad for a vehicle that has been in production since 1979.
