It the worst experience of buying a car!!! My boyfriend I tried to ask about how to buy a car. Because I am an international student, and I was not sure about the process, so I wanted to ask. But the person who helped us kept interrupting us while we talked. He said I could not apply for it because I did not have SSN, which I could understand. However, that person was rude to my bf. He's credit score was not that good, but the person started saying "why your score is so bad?" "where did you get this score from?" "I've never seen this bad score"...etc. While he should be giving his professional options for us to purchase a car, he was judging the credit score. I was very angry about it. He said we might need to pay 5 thousand for down payment, and we said we could try to do it, and we asked for test drive. But he said there was no point for us to do that because we were not buying the car right away. Then we went to the Honda next door, there customer service was way better than Toyota.
It is such a terrible experience I had with Toyota, and I will never go there again!
