Private Car Sale in NH?

[bigdog]

I'm purchasing a new car next week, and undecided whether to take the Dealer trade or sell my car myself.

I know trading makes more sense and a lot less hassle, but may be able to make considerable more selling the car myself. The car is fairly good shape, and would sell on Craigslist.

In Mass......
I know 'private' car sales have the same 30 day warranty, as if a dealer sells the car. There is no such thing as selling a car in Mass. 'as is' anymore.
The car also must pass MA State inspection. If the car doesn't pass inspection, the buyer has the right to return the car to you for a full refund of money,
if it requires more than 10% of the puchase price in repairs to get the car to pass inspection.

I'm not saying that my car won't pass inspection, but once it's sold I do't want it back to repeat the circle.

I know here is a 'leomon law' in NH, but I believe this only applies to 'new' cars.
What is the 'private' car sale regulations in N.H. ?

Thanks,
