Event Generator and manufacturer races sometimes pick the 2P version of Autumn Ring, which has several props like stands and signs removed to improve performance.On Autumn Ring's last corners there sometimes is and sometimes is not a spectators stands. 2 different races pictured
I may have cracked that case: the Camaro is what you normally face in the Seattle Circuit endurance. The reason why it appears in Tahiti Maze in US v1.0 is that it's affected by the "shifted by one" mistake that also gets the Vector M12 LM, Citroën Xantia and others in the wrong races. It is the last car on the JP opponent list, and is followed by the Exxon 206 on the US list.Also between JP 1.0 & US 1.0, they added a Camaro Z28 as a potential opponent to the Tahiti Maze Dirt Event where you race the 206. Seems they were trying to add a second 206 Rally Car entry for the other colour livery and ended up putting the wrong car id (since that's what it was changed to for subsequent releases). I can't get it to appear though, no matter how many times I exit and restart the race.
