Do I have a right if the car was sold way below fair market value?

It depends on the circumstances. In general, if you sell an item for a price that you agree to, then there is no legal issue, even if the price was below fair market value. However, there are some exceptions to this rule.

For example, if the buyer:

- misrepresented the value of the car, or

- took advantage of your vulnerability (e.g., you were in financial distress),

then you may have grounds to sue for rescission of the contract (i.e., to have the sale canceled).

Additionally, some states have laws that protect consumers from unfair or deceptive trade practices. These laws may give you rights even if the buyer did not intentionally mislead you.

If you are thinking about suing over the sale of a car, it is important to speak to a lawyer to discuss your specific circumstances and to determine whether you have a valid claim.
