Checking out a new car's competition from the used-car market.
This week, we'll be using the 2014 Cadillac CTS Vsport for our control. It's an immensely powerful luxury sedan, thanks in part to its 420-horsepower, twin-turbo V-6. All that power is sent through the rear wheels, hustling the Vsport to 60 in under 4 seconds. It's a serious performance sedan, with middling gas mileage and an interior that's awfully luxurious. It's a jack of many trades, so can it be bested by a master?
