OP again.

well i hope if i do reach the final race, i have more than one or two keys left to do it lol.

also, why you gotta farm 5 million though ? 4 free upgrades from the RnD rewards itself. plus look for any S-class upgrade from mastery rewards that you can use now. i'll be upgrading the RUF CTR sufficiently so that i can get its mastery-10 S class upgrade, and also buy the spano (old one of course lol) and upgrade it sufficiently so that i can get its mastery-5 and 10 S-class upgrades..thats saves me a lot of credits..besides, i always focus entirely on upgrading top speeds and nitro only (same when pro-ing) and dont touch accel and handling unless absolutely required (and often maxing them is never required)..so if that works out as well i'll be saving a lot of credits.
