On Monday no dealership has any cars to sell so it’s a mute point at the moment
But yes it gets the name out there, in front of mind, etc…
Adds something to your name etc…
People involved get to go to the track and have a good time. So it increases engagement.
It isn’t, if it ever has been, literally win on Sunday nip down to the shops and pick one up on Monday.
Basically as said above by 505 and 96.
