Just incase your not aware of it, some cars might only be ran a few times and never used again so you won’t need to upgrade all your cars. Be careful on your upgrading and save your gold for later when it is needed most. A lot of people don’t complete each series to 100% right away. They stop at 75% because it costs so much more gold for the last upgrades then complete the series later.
