NEW YORK Help! Selling a car private party this morning (Saturday) - but are BOTH buyer and seller are supposed to visit the DMV together to file DTF-802 (title transfer/sales tax)? It's SATURDAY. Does this mean it's not possible to sell a car private party on a weekend?

I just want to sell the car today, cash. Guy will be here in less than 2 hours.

Went to DMV and got the DTF-802, and they walked me through it and marked the sections I needed to fill out and sign, but they did NOT mark section 5 (purchase information) and nothing about sales tax due.

Online I'm reading that Buyer and Seller need to visit the DMV together?? That seems wholly impractical and impossible on a Saturday. What do I do?
