I've got at least 1 star in all levels, and I am working through the 2 stars on all levels. I've been getting treasure chests as I can find them or figure out how to get them.
Will the money earned from 3 stars and all treasure chests buy all the upgrades?
I'm thinking there's still going to be a lot of grinding to pay for some upgrades to max out all the cars, or perhaps to get upgrades just to get that 3rd star.
Does the 3rd star require the full upgrades to get in some cases?
