My daughter and I purchased a pre-owned vehicle from this dealer recently, and the car is fine, however the experience was very poor, and I will never go back. I know I could have walked away at any time, but she wanted the car and it was priced well.
First of all, I was placing a good amount down and had my own financing for the remainder. Despite this, I was asked by the sales person to fill out "just the first five lines" of a credit application. Everything on these lines was on my drivers license which they had made a copy of and on the offer form with one notable exception, my social security number. I absolutely refused to provide it as they have no need for it. We went back and forth with her stating the five lines were required for "identity proof", which is pure nonsense. I know they were going to send me to finance and wanted that to run a soft check behind my back (or worse, an unauthorized hard check). After back and forth, with her seeing her manager, they relented on this.
We were then sent to the finance person, Tammy Chan. This experience alone prompted me to write this review and score this place the way I have. She was rude at best. I immediately told her I was putting down "X" and that I had my own financing for the remainder. She responded that she could get me a better rate then what I had. I asked to tell me exactly what that was and she asked if my credit score was above 800, and I told her it was. She gave me a rate, throwing in "if your score is above 800" in a tone that insinuated it was not, but then told me if I would purchase an extended warranty for $2500 she could get me an even lower rate. She was very condescending and when I told her I understood finance and the savings in interest did not come close to paying the $2500, PLUS the car I bought still had 3 years and 15,000 miles on the bumper to bumper, she got visibly upset and told me I was wrong on the warranty. Then she pulled out a book and looked it up. I was correct. After she finally got it through her head I was not buying a warranty that was about 20% of the cost of the car, she never brought up the original rate she quoted me and finished the deal. She was curt and rude. I'll never go back and encourage others to stay away as well.
