I can only tell my experience. I started by talking to my contact person every month for the first 3 months then called every week for a few months. Then they called me with weekly updates until 04/19/95 when my Jeep rolled off the assembly line .04/19 just happens to be my birthday . Cool birthday present. I still have it but it has transformed into a RockCrawler stroked to 4.6 , NV4500, Atlas II , BFG Krawlers yada yada .
