I thought Chuck had a sign up form on the web site for adding cars, but you might just have to send him an email. He does not update it very often, so don't look for your info to pop up to soon. Though you never know if you happened to send him your info and the next day was THE DAY he updated then you would be on right away, otherwise you might have to wait 6+ months for him to update again.
Chuck has a lot of irons in the fire, so he has a hard time keeping it as up to date as I know he would like, but he does it for free as a service to the 928 community so no bitching is allowed or tolerated...at least not by ME! His service to the 928 community and club have been outstanding so enjoy what he has done there and be thankful for Chuck Z! I know I am!
