If you are interested in buying a powerful, high performance luxury car, but you want to stick to a budget, buying a used BMW M3 may be a great option for you. The newest M3 model comes in three trims, the M3 Convertible, the M3 Coupe and the M3 Sedan. All M3 trims come with a 4 liter, V-8 engine that runs at 414 horsepower. The only downside to such a powerful engine is its fuel efficiency, and the BMW M3 leaves something to be desired with only 20 miles per gallon on the highway for the Coupe and Sedan trims, and 19 miles per gallon on the highway for the Convertible, because it is less aerodynamic. The fact that BMW doesn't even advertise this model's city mileage on its website indicates that it is also probably really bad. However, what the BMW M3 lacks in fuel efficiency is more than made up for by its power and class. Featured in the interior of the M3 are an excellent sound system with radio, CD and MP3 capabilities, Novillo Leather upholstery and power-adjustable seats. The car also comes with automatic headlight control, rain-sensing windshield wipers and a multi-function remote control that makes adjusting the temperature, locking or unlocking the doors and adjusting the heat pads in the seat easy and convenient. This model is a good choice for people who like a fast and smooth ride in a sporty, luxurious car.
