<prompt> Human: So my last car was totaled, and the title was in my sisters name as my family does a lot of car trading. I found a new car I wanted today and asked about payment options since the insurance check is currently going to my sister. She is away on her honeymoon for another week. The salesman said that I can write a check in full and if I can prove I have the money coming to me Which I will as soon as my sister gets back they will wait to deposit the check, I feel like this is kinda sketch, but this is my first car buying experience and wanted to ask here for some advice. The car is a used Hyundai from one of their dealerships  <response>: It kinda depends on how much you trust the dealership. If you buy the car, you owe them money, and a check represents a written promise to pay that money. If the only thing youve got is a verbal promise, that leaves you on sorta shaky ground. If you are set on buying that car and dont need it right now, offer to make a holding deposit so that you can buy the car for the price you agreed on when your sister gets back. Make sure to get the price and deposit amount in writing.
