Famously, none of the upgrades can really be accommodated in the original box, so I think BB might be the perfect solution - take out the insert, a bin for the cars, a bin for the weather and track condition tokens, reg. card boxes for the player decks + gear shift icons, big card boxes for the heat/stress/garage/sponsorship cards
I'm picturing removing the tray insert in the original box, all the BB components lay flat at the bottom of the box and stack the player mats and boards on top?
