Interesting idea! Where do you find all that information?
Allocations are, from what I have seen, the 15th and 30th of the month (give or take.) They start showing up on dealership websites up to 6 days later...so the August 15th allocation appeared in the local dealer "stock" by/around the 21th, the 30th by/around the 6th.
I write down the VIN, trim, color, stock # (if assigned) and have an Excel spreadsheet tab for each dealership.
In 1-2 allocation cycles, one of three things will happen -
1. A Monroney will be uploaded with the dealer's name on it and the dealership is shipped the rig
2. A Monroney is generated for the dealership but the rig is later reassigned anyway or the converse where another dealer's Monroney is reassigned to a local dealer's stock (I don't know if this is Toyota doing it or if it is a dealer swap - either way this has not happened often.)
3. A Monroney is never generated and the VIN magically disappears from the dealer's "stock." Where did Toyota reassign that rig to, who knows? Doing a Google search using the original VIN leads to a dead end.
I invest about 30 minutes a week doing this. If the dealer I have a deposit with starts pulling BS on my reservation, I'll list the seven (7!) 2023 allocations that have disappeared since MY23 started in August, point out the local dealership that has yet to lose a single allocation and ask them if they want to lose my sale to that rival batting a thousand because I'm not here to play games...
I don't want to gain a dominant position over the dealerships in this transaction. I do insist on a position of equality and information is a good way to level the score.
