BMW X3: The BMW X3 is a compact luxury crossover SUV manufactured by German automaker BMW since 2003.  Based on the BMW 3 Series platform, and now in its third generation, BMW markets the crossover as a "Sports Activity Vehicle", the company's proprietary descriptor for its X-line of vehicles.  The first generation X3 was designed by BMW in conjunction with Magna Steyr of Graz, Austria—who also manufactured all X3s under contract to BMW.  BMW manufactures the second generation X3 at their Spartanburg plant in South Carolina, United States.

BMW M4: The BMW M4 is a high-performance version of the BMW 4 Series automobile developed by BMW's motorsport division, the BMW M GmbH.  Part of the renumbering that splits the 3 Series coupe and convertible models to the 4 Series (to further differentiate it from the 3 Series), the M4 replaced the M3 Coupe and Convertible models.  Upgrades over the standard BMW 4-Series include: a very powerful and responsive, twin turbocharged engine; improved handling, suspension, and braking systems; aerodynamic body enhancements; interior/exterior accents with the tri-colour "M" (Motorsport) badging; the significantly reduced weight compared to the standard 4 series and its predecessor with an all-new stiffer chassis and extensive use of carbon fiber, especially the roof of the car.
