Seasonal race car selections

I entered the off road buggies championship hoping to use one of my volkswagons. But it made me buy the alumacraft buggie (100k). And that was it i could choose. Even though i was racing against the Volkswagens i have in the garage. Mine are still stock too. I just entered the classic muscle seasonal championship and almost the same thing. I have to buy one of four other cars, 2 vettes the dart and falcon. when i have six cars in that class already. Whats the deal? Is it me or are these locked car selections to make you buy more cars i don’t want. Anybody got ideas??

Either one of the many bugs of this game or your cars weren’t the right class. I think there’s not only a type of car limitation but class. I did the buggies in a B-class buggy and the Muscle cars in a C class '69 Mustang. Not playing atm so I can’t check myself but worth a look.

I see that the index is too high on 2 cars, but whats range for below? Its a b class 700 race and i have 603 gnx?

Figured it out, PI was far off on my classic muscle cars and the gnx is a retro. Rant over, lol!!
