The only way to guarantee exact same area parking is to get there around 330am. The Corvette club was where we were last time.
I heard a guy say he got there at 415 and they had already coned off a huge number of spots, which technically is against the rules but there is no way to enforce. Thus we park in the same general section, but same actual spots is next to impossible. If your not there by 7, as cones are supposed to be pulled by then which everyone generally does by 715, your too late and every empty spot is taken up. Only the exotics and porsches can show up late because most of the time there are less of them than total allotted spots in their two parking areas, sometimes though the spots are full and you'll see a Ferrari mixed in with Honda's.
