> Payment grids for one VIN — term, rate, and money down as posted scenarios, F&I lines attached where papered — the same grid on both sides of the desk.

The deal structure on one page: payment grids for any VIN — term by rate by money down — with the trade, the taxes, and every F&I attach line posted as its own line. The desk's math with every line showing; the customer reads the same grid the desk reads. The structure settles as one order at commerce.vin. Grid reads are free.
