By the way, for those that can't get enough "Car Stuff" in one day... There is the Cars and Coffee show in Irvine located just a few miles away. It goes from 7-9 AM every Saturday morning. If you are up at the crack of dawn anyway you could hit that and still make it to the McDonalds for the drive in plenty of time.
I think I will do that, actually... And duck out a little early - like 8:30 or so - to be at the Macs to meet all the folks.
