BMW Australia has pulled out the red pen for the pricing of its 2011 3 Series range, slashing prices by up to 11 percent for many of its petrol models – including the M3.Marking what it describes as the 3 Series’ success as “the world’s most successful premium model series,” BMW Australia has cut prices on a number of Sedan, Touring, Coupe and Convertible models.As part of the changes, the 325i has also gained BMW’s Innovations package as standard, which adds Navigation System Professional, Voice Control, High-Beam Assist, Bi-Xenon headlights (with washer system) and power folding exterior mirrors (with automatic anti-dazzle function).The new features join the existing standard Exclusive package, which includes 17-inch alloy wheels, fine-wood trim and roof rails.The 3 Series is currently the second best-selling mid-size premium car in Australia. With 405 sales across the 3 Series range in March, it led the Audi A4 (330) by 75 cars and the Lexus IS range (267) by 138 cars, but lagged behind the Mercedes-Benz C-Class (631) by 226 cars.The 3 Series accounted for 37 percent of total BMW sales in 2010.
