If you go to a car show and you ask a person if they are wanting to sell their car and they give a price that you can afford you should buy the car on the spot because there is so much more that you can do to the car after you buy it from the person at the event. You can do all kinds of things to it that you wouldn't even know about but you need to be careful when buying vehicles from a car show member.
Some of the automobiles at the car show are really old and just look nice so that is one of the reasons why you need to be careful. You could be buying a nice car with big rims and TVs but it could have like a lot of miles on it and therefore would probably be the reason why the seller is selling for so cheap or the price that you like so much.
Unless you know the person that is selling the vehicle then I think you shouldn't buy an automobile from a car show. There are just so many things that can go wrong, the vehicle can break down right after they sold it to you and you will have no idea what the problem is. There are just numerous different things that can go wrong with buying at an automotive show.
Another thing just because the vehicle looks nice and runs good doesn't mean it is a good car. Just because you want it from a person at an automobile event doesn't mean anything either. Just remember they won't have the time to stop and go over every little detail with you at the car show so remember that. They might just be trying to sell really fast for quick cash.
The other major con about buying a from an automobile show is that you will not be able to take a test drive unless the person is leaving the event and you demand a test drive. It is highly likely that they will say no unless you just want a test drive of them driving the vehicle you are wanting to buy so much.
The point is if you really want a vehicle from a car show and you are willing to pay the price that they are offering then all you need to do is get the person's contact info and just get up with them afterwards to start test driving and negotiating about the automobile and the price. Even though it is a nice ride after test driving it and seeing it all around in and out you might not want it so badly, you might find something else that catches your eye.
