Thanks everyone. They showed up with a bag full of cash. I had them hold onto it and took them to the bank and let the cashier count it. Let's just say I was at the bank for a while letting that poor guy count out the cash. Put it straight into my account and then came back to hand over the car. They didn't even want to take it for a test ride, or even start it for that matter. They told me it's the first time they have ever gone to a private seller and the car turned out to be "as advertised". It almost brought a tear to my eyes watching it drive away.
They literally had a bag full of 1's, 5's, 10's, 20's, 50's, and 100's just thrown into a garbage bag. The teller was not happy and I'm surprised that he didn't send us on our way, but it was too big a deposit to let us walk away and I have too much in that bank for them to piss me off. Well, now it's time to cancel the insurance.
