Haven’t seen any one talking about this. The Forzathon shop in city center near Casa Bella is interactive during the Eliminator. Entering and exiting this makes everything in the game interactive - thus enabling you to access your home and choose freely from all your cars.
Head to heads will always result in a loss, even if you come first, yet the final race works as intended even if you breeze past everyone in your Jesko.
You also show up as the level 1 Beetle above your name tag in head to heads, resulting in easy completion of the accolade regarding beating 3 levels above you.
Eliminator is now even more of a mess.
