GUMBALL 3000 IN MÉXICO (Looking For tips and spoilers)

Hey guys!
Next year’s my first time going to San Miguel de Allende for the Gumball 3000 rally.
Anyone who’s already been, hit me with:
What time do the cars usually arrive?
Where’s the best place to be?
Any spoilers about what cars might be there?
General tips (when to get there, where to stand, etc.)

I'm honestly very excited right now, and yes, it will be worth the wait.
