My 18 year old son & I just got back from O'fest in New Hampshire. We drove the almost stock '94 530i. We both did the gymkana,auto-x & safety school. Trey had better times in auto-x than some guy in a 2001 Dinan M5 & he entered the concurs (clean car class) & got an honorable mention, our 3rd BMW trophy in 2 years.
