We stopped by an RV dealership and the salesperson, after much discussion, showed us a used RV on the internet. We would have to wait for several days to see it because it was in another state but someone would drive it up to PA for us. We signed the purchase agreement, which included wording to the effect that we would accept the RV if it was as pictured. We gave them a down payment. After we left, we found the same exact model on the internet for $50,000 less!!!!!!!!!!! Yes, that is fifty thousand dollars less than what we agreed to pay. We have not seen the RV yet, as it has not been delivered to the dealership. Can we break this contract? How??
