I want to know if I can sell it as is or if I have to warrantee anything?? Does it depend on value of car or milage? What should I know before selling my car?

Sell the car "As Is", and make no representations about how well it will perform in the future. If it has a defect, be up front about it. Check this: Vehicle Registration and Title Information

Make the agreement in writing, keep a copy ( forever) you may warranty what you want, or provide no warranty,

You are a private person not a new car dealer or a used car dealer who offers warranties on vehicles. If the car has a mechanical problem that you are aware of, by all means disclose this fact to the buyer. You are selling the used car "as is" and do not have to give a warranty on the vehicle.

While telling the buyer everything you know is wrong with the vehicle is probably the moral thing to do, I would venture to say that no one does that, or at least no more than 1 out of 10.

I look at it this way.

You have a car to sell. Someone else wants to buy a car.

You show them the car. You offer them the chance to test drive the car. You offer them the opportunity to have the car checked out by their own mechanic. You don't make any statements about the reliability of the car. If they ASK about something, that you are aware of, you answer it truthfully.

For example, "does it burn any oil"? "Well, I haven't seen any smoke out the tail pipe, and I usually make it to my next 3,000 mile oil change without having to add any, so I don't think so".

It is the responsibility of the buyer, to make certain that what they are about to purchase meets the standards they expect, for the price you are asking.

Just my opinion, I'll probably get called a name or two, but, oh well.
