I'm totally confused in GT5. I'm at Level 7 in Spec-A, I haven't played Spec-B driving yet. I all ready won the Top Gear Test Track race with the VW Vans with a silver trophy, and just completed the AMG SL300 on the first part of the N?rburgring Nordschleife. So, how do I get to run whatever car I want on the Top Gear Test Track? In Arcade/Single Player, the track isn't showing up there.
