Seems other people have reached this roadblock aswell.
Just started season 7, race 3 and comes up with a message stating i have no cars or need to level up to continue. It doesnt let me see the restriction or what cars to use so ive changed my cars class to other classes but still cant get back in. Ive continued on the event list but then i wont complete the seasons.any help. ive even checked my saved games for any corrupt files but nope.

Sorry man i got no idea, im in season 7 race 2 and i hope this doesnt happen with me cause i have only 3 cars i think...and i dont really feel like starting over again..let me know if you find out how to fix this.

is forza any good guys?

the only class i havnt tried is X class. sounds like it could be a specific manufacturer race. let me know when you get to the next race dude

@Chef

Yea man its heaps good, im not a racing fan and i love it!

yeah its done well. if you love cars. amazing visuals, sounds are spot on, cars handle great, tons of mods. tons of extras and life

what is the event called ? it is probably manufacturer specific or if it's GT2 then only a certain few cars can enter.

its on road atlanta. 3rd race of 17. season 7 race 3. thats all i can see

@ Ali3n, i just got up to that race and you have to have a Chervot or however you spell it, its got the gold symbol and make it a A class one also.

any chev?

yep any chev worked. thanks guys
