Dick's Hillsboro Hyundai

We purchased a truck from Dick's Hillsboro Hyundai in February. Although their actions were 100% legal, they are unethical. We had already been approved for a loan through our bank, the sales guy insisted that he could get us a better deal and that the dealer HAS to run a credit inquiry even though we already had the loan approval forms. We did not want our credit to be hurt by too many credit inquiries and he promised that they would only submit it to a couple banks. My husband had over 10 inquiries hit his credit from them! The sales guy asked us what we owed on our trade in, we were unsure of the exact amount and he told us that we could give him an estimate within $500 of the balance owed. In late June, were sent a bill stating that the car dealership had made multiple attempts to contact us and that we owed $438.41 on the balance of our loan for the trade in and if we did not respond within a certain amount of time, that they were going to send the bill to collections. We know this is untrue because we had been back to the dealership multiple times regarding problems with the truck. They even refunded us over $600, in May, when the truck broke down on the mountain and had to be repaired in Sandy. My husband went into the dealership and gave them his card information so that they could auto deduct the $438.41 on the first of July. That never happened but instead we received a collections letter saying that we still hadn't paid the bill. Like I said they were well within their legal rights, but was it right? NO. We will never do business with any form of Dicks Auto Group ever again.
