Among the planet's most desirable cars, the Aston Martin Vanquish occupies an enviable place, even though it's no spring chicken. Whether it's the coupe or the cabriolet, this GT devours kilometre after kilometre with uncommon ease. Its 6.0L V12 shamelessly runs on super unleaded—to the tune of over 16 L/100 km in the city and 10.7 on the highway, but when you're ready to pay over $300,000 for a car, fuel consumption is but a very minor detail.
