BMW tuner Vorsteiner, in conjunction with Oakley, held a customer appreciation event at Oakley's Foothill Ranch HQ. Besides the hundreds of tweaked BMWs on hand, a few dozen Porsches, Ferraris and Lamborghinis also showed up for the party. Complimentary In-N-Out burgers, Starbucks coffee and Monster energy drinks kept the crowd energized, tours of the facility were available, and there was even a drawing for parts and services, all free to anyone who showed up. Pretty cool event at a really sweet locale.
