MARK ROBERTSON: Father of BETSY, Jake, Danny and Bill. Evil stepfather of ALANIA and Anthony. He is the husband of Julie Robertson. He is a Computer Geek. His life's ambition is to have one car that runs.. for more than a month. Preferably the 57 Chev Nomad in his garage that he forgot to tell Julie about. That and the Bronco in the back yard he got after the got rid of the 2 Cadillac's, the nissan and I don't remember the other one. Julie's car runs…Quite well. She has the service station fix it.. Maybe if they could put a 400mhz processor in his car he could make it run.
