I keep reading these threads and there is a common theme; someone didnt represent this or that correctly and now they have to make it right.
Indeed you should represent the car to the best of your knowledge and say so, and here is a really unique idea- How about a Bill of sale. You can download one off the web or even the DMV and all you need to do is add wording that says the buyer had the right to inspect and is accepting the vehicle in "as is" condition. And it doesnt have to be notarized, it can be witnessed.
Its not that big of a deal and I know that typing it in MS WORD is not a challenge as everyone can bang the keyboards on this forum.
If you dont sell the vehicle with a piece of paper confirming the deal and protecting yourself; then really who should you blame?
Easy answer. Yourself.
