Famous for making cars as sleek as they are impossibly expensive, automobili lamborghini (a subsidiary of volkswagen's audi unit) caters to the elite consumer. for a mere $300,000, you can buy one of the 400 or so lamborghini murciélagos manufactured each year. tired of poor acceleration? with a top speed of more than 200 mph, the murciélago's 6.5-liter, 12-cylinder power plant (which delivers 630 horsepower -- more than five toyota corollas or two ford v-8s) can rocket you from zero to 60 mph in less than four seconds. but don't burn too much rubber -- the murciélago's pirelli tires cost more than $600 each.
