THE new C-Class has prompted BMW to throw more equipment at its 3 Series line-up. All now come with head-up display, lane-departure warning, reversing camera and pedestrian warning with light braking function. And all but the base 316i get adaptive dampers and 10mm-lower suspension (hooray!). Prices rise on most models by about $1000, although the 335i, Active Hybrid 3 and M3 dodge the increases. The 3 GT is now cheaper, narrowing the price gap to the 3 Series Touring to $2100.
