Can anyone give me some advice, I have recently sold a used car and now the

[jp_tp]

buyers want their money back.? Days after selling the car the buyers contacted me stating the body was rusted out and either I give back their money or they would sue me. The car is 18yrs old and was listed as in running condition, but upon viewing the car anyone could see that it was definately used for its 18yrs. The car was sold "AS IS" so does anyone know who may have the upper hand in this case? Im in the state of Ohio and have researched "LEMON LAWS" but I havent come up with much.
