Most Expensive Convertible: 2009 Mercedes-Benz McLaren SLR 722 Roadster
MSRP: $548,000 (includes $3000 gas guzzler tax)
Fun fact: Daimler builds both the least and most expensive convertibles offered in America. The 2009 Mercedes-Benz McLaren SLR 722 Roadster carries a base price that exceeds half a million dollars, and that's not even counting the extra $3000 Uncle Sam tacks on as a gas-guzzler tax.
For those who can afford that exorbitant figure, it's worth it. The SLR 722 makes use of a hand-built supercharged 5.5-liter V-8, balanced perfectly amidships. It's good for a whopping 641 hp, which catapults the car from 0-62 mph in 3.6 seconds, and ultimately to a top speed of 209 mph.
That sum also buys considerable exclusivity. Only 75 examples of the SLR 722 roadster will be built, with only a handful - approximately 20 - coming to the U.S.A. After that, the SLR is no more in North America, although other markets receive the insane SLR Stirling Moss model (which is not only topless but also virtually windshield-less) as a farewell to the Anglo-Germanic supercar.
