Consumer Vehicle Returns and Misrepresentations in Virginia

This legal question related to consumer law attorneys in VirginiaMinnesota has been answered.

If you return a previously bought vehicle within 24 hrs, and the salesman tell you, "YOU CANNOT" cancel with that 24 hr. and I believed him and kept the vehicle can I sue for the balance of the loan I took out? and return the car months later?? 

I financed a truck, the check engine light came on later that day, the next morning I returned the truck, I wanted to cancel and purchase another truck at same dealership without a check engine light on, ( within 24 hours) salesman says in his own words: It's to late I cant cancel (turns out to be a lie) he and his lawyers says dmv law says once I sign the agreement I own it, also a written agreement to relace running boards and part of purchase agreement, then changed words to repair on docs. but running boards are un repairable, so refused to relaced running boards. and fix check engine light.  im talking them to small claims court, (to  fix catalytic converter and running boards) should I have taken them to another court?  what the significance of him lying to me that I could not cancel the purchase that was clearly within the24 hrs, because I would have returned it if I could have. could I sue to return the truck? or pay the remaining balance of the loan I took out?
