So with my love for Guardians of The Galaxy skyrocketing I realized that this is the one Kingdom Hearts/Marvel crossover that I could get behind 100%. The Guardians travel through space, just imagine if they would pop into worlds while Sora and co. were adventuring. It would be glorious! These two might not think so at the moment though.
There is a Pope in the Cars universe. This means that there is Catholic Christianity, which means there was a Jesus car who was crucified. Jesus Chrysler was crucified by car Romans under Pontiac Pilot who washed his wheels. A car was nailed to a cross and ascended to Heaven.
