What are your liabilities when selling an "as is" vehicle?

Not much. So long as you can legally transfer the vehicle and you don't make any warranties or representations (which you should always put in writing anyway), you should be OK. To be doubly safe, offer to take the car to any shop of their choice (at their expense) so they can have it checked out by their own mechanic. Put that in writing too. If anything goes wrong after that, you'll be as close to bullet proof as is possible.

Even when you sell a car "as is" you are still selling it as a car. If you say it runs then you are saying it is suitable for a particular purpose. If a person buys it and finds out it does not run, or does not even start, then it was not suitable for that purpose and they will have a (weak) claim against you.

What you need to say is the sale is "as is" and you make no guarantees, warranties or other pledges on the vehicle. The best way is to say you are selling it as a parts vehicle. Then they would feel they were lucky if it runs.

Depends where you are. In most places, none.

In some States, it is illegal to sell a registered vehicle that cannot pass a smog or safety check. You must either do sufficient repairs to enable it to pass before selling it, or surrender the plates and sell it as 'non-op'.

If you sell it with plates, and it fails smog or safety, then in such a State you may be liable to the buyer for the cost of repairs to make it legal.
