Our Lamborghini Murcielago LP640 Roadster carried a base price of $351,700 including the $1,300 destination charge and $5,400 in gas-guzzler taxes. To that, more than $50,000 in options was added to bring the final tally to $404,835. Hermera alloy wheels, carbon fiber trim, ceramic brakes, and the E-gear transmission accounted for the bulk of the extra cost.
