For the last couple of years, Bimmerfest has established itself as the largest BMW gathering in the world. With the success of the E90/E92/E93 platform, it's easy to see how BMW has branched off to a whole new demographic and group of enthusiasts. It's also no surprise that Bimmerfest was jam packed with this chassis, along with plenty of 5-Series, 6-Series, E36s and E46s. We remember attending Bimmerfest five years ago at a BMW dealership in Santa Barbara, and to see how far it has come in five years is simply astounding. This year they held it at the infamous Rose Bowl in Pasadena, California. And while there were no Trojans or Bruins around, there were plenty of BMW roundels to go around.
