Driver Bio: | Michael Vaughan and Phil Thain Sr; Just a couple of old guys trying to have fun. Trying to keep the car as old school as we can, go as fast as possible, and still be able to drive it to and from the track. With time, and money we will be making improvements with the hopes of moving down in the ET clubs. |
