The ultimate summer action event has arrived in the form of Extreme Autofest at Qualcomm Stadium in San Diego. Feast your eyes on hundreds of tricked-out rides ranging from lifted 4x4 trucks with insane paint jobs to customized motorcycles, to the jaw-dropping Lowrider Car Hop demonstration. Check out cars from Honda, Toyota, Ford, Dodge and more that have been turned into veritable Swiss Army knives of customized features as their designers compete for cash and cool prizes. And the vehicular madness is only the beginning: Extreme Autofest also includes a performance from Xzibit, the HeyBaby of California Bikini Contest and live concerts throughout the day.
