Want a luxury car without having to pay for premium gas? We can't blame you. As of March 21, a gallon of premium averaged $3.87 nationwide, according to AAA. That's 35 cents more than a gallon of the cheap stuff. Drive 15,000 miles a year at 25 mpg, and the premium, er, premium adds up to $210.
Luxury brands often charge extra — sometimes absurd amounts — for premium extravagances, and gas is no exception. Most luxury-car owners are accustomed to paying extra for premium fuel, which higher-compression engines often prefer.
