Beaverton Hyundai

We bought a Hyundai Elantra from Beaverton Hyundai. At the end of the buying, they changed the interest rate to a higher rate without telling us that they did it from the agreement that we made, which we found out at the signing of the contract. Our agreement was that we would get Alloy Rims with the car instead of the plastic ones. This also wasn't listed in the contract when we went to sign it and we had to have them add this. We went to our appointment to have our tires put on, there were no tires for us and they informed us that they didn't know when they were going to get tires and what did we want them to do about it. Secondly, the tags were to be covered by them and they told me that they were at the front desk waiting. There were no tags or plates waiting as the lady had told me the day before. I would not buy with them. They don't follow through on their obligations once the money has crossed hands.
