Jeremy, a reader of BMWBLOG, spotted the new 2012 BMW 3 Series in La Quinta, California. The 328i model sports the Alpine White paint and the U.S. license plate mounting base that had many fans worried. It remains unknown if the removable mountain base will come standard or will be installed by request.

The new F30 3 Series will make its U.S. debut next month with two models: the 328i and the more powerful 335i.

As we announced before, the base price of the 2012 328i Sedan is $34,900 and the 335i Sedan is $42,400. This represents a $300 and $350 base price increases versus the outgoing model. The 3 Series now includes standards features such as 6.5” display with iDrive controller, Bluetooth connectivity, USB/iPod interface, 8-Speed Automatic Transmission, Automatic Start/Stop, Dynamic Driving Control with ECO PRO Mode, Brake Energy Regeneration, and a 1” standard wheel size increase.

The Modern Line (ZML) and Luxury Line (ZLL) will sell for an additional $2,100 for the 328i and $1,400 for the 335i model.  The Sport Line (ZSL) will make you spend $2,500 for the 328i and $1,700 for 335i.

The sixth generation of the 3 Series has grown moderately in size compared to its predecessor, with its wide track (front + 37 mm/1.46 in., rear + 47 mm/1.85 in.) particularly prominent, and the car’s length (+ 93 mm/3.66 in.) and wheelbase (+ 50 mm/1.96 in.) also accentuates its sporting allure. The car’s larger dimensions ensure rear passengers are welcomed by 0.71 in. /18 mm of extra legroom inside the doors as they climb aboard. Behind the fully contoured front seats, 0.6 in / 15 mm of additional knee room and 0.31in. / 8 mm of extra headroom further enhance the passengers’ comfort on the road.

The M Sport Package will be available at launch time as well and will bring the ultimate in sporting makeovers to the new BMW 3 Series. An all-new aerodynamic package for the exterior clearly sets cars specified with this package apart from the base model and the three lines. 18 and 19 -inch light-alloy wheels in hallmark M design, M Sport suspension, a black kidney grille and BMW Individual High-gloss Shadowline trim give the car that typical M look. The theme continues inside the car with sports seats boasting distinctive upholstery choices, trim elements with blue accent strips, an M Short-shifter (in models with manual gearbox), M door sill covers, an M driver’s footrest and the new M leather steering wheel.

Stay tuned for an exclusive test drive of the 2012 BMW 335i. In the mean time, catch our review of the 328i.
