<prompt> Human: My dad just told me that at dealerships in CA, you have 5 days to pay for a car if you pay in cash i.e. you hand them a check for 10k, and you can legally drive it off the lot and pay the remaining 8k of the total cash price within 5 days. I cannot find any information on the internet about this. Can anyone verify this? Also, can anyone tell me if this applies in other states? I am looking to purchase a car in WI.  <response>: Ive never heard of such a thing. I dont imagine this being a legal question, but a policy question. A law saying you must be allowed to take a car that you are going to, but have not yet, paid cash for, doesnt make a lot of sense to me. Though I can imagine a dealership letting you put a deposit and take the car because if you leave without the car youre more likely to change your mind.Its not something I would rely on being an option. Id call a dealership and ask.
