Can a used car dealer sell a car knowing it had a broken speedometer?

If your daughter is a minor, the contract for sale might be void because minor's cannot make contracts. If not, your daughter likely has only fraud allegations to make.

There are state and federal laws that require a dealer to disclose speedometer discrepancies. (I don't practice in this area of the law, but I thought that it was interesting so I checked).. Ohio DOES have a law. See attached link. The key is that a person cannot transfer a car without disclosing the fact that the odometer is not properly functioning. The question is, when does a transfer occur? The statute (attached) says, when ownership changes (duh), but it SEEMS as though ownership changed, even though title hadn't transferred, when the agreement to purchase the car was signed and the money was paid. I recommend that you check with a local consumer law attorney who can help you. There are big penalties for dealers who do bad things like this. A friend of mine had a case where the dealer had a typo on the title actually saying that the mileage was slightly higher that reality (they transposed two the hundreds and tens numerals in the mileage disclosure, making the car appear WORSE than it really was. Still it is a technical violation. The buyer still sued and the dealer paid her some real money. Check for a local consumer attorney. They should be able to give you the help you need. Consumer laws like these often let you recover attorneys fees, as well as damages. The consumer lawyer should know.
