I had a terrible experience buying a new car. I went in with a Honda Pilot to trade in and was told by a Sales Rep that I could get up to 25K as trade in. They asked me to come the next day as they were short staffed. The next day had an appointment but still made me wait for 2 hours and at the end they came up with a trade in value of 18500 (adding a 1K bonus) and I had no idea why it would go down so much and they won't budge on the price which included all the unnecessary add ons and wanted me to pay sticker price.
I tried calling and emailing their Sales Manager Adam Rutledge, but apparently he won't return calls or emails.
I ended going to Honda Cars of Denton for my purchase. I wasted a lot of time here and the Sales Experience was absolutely undesirable and unacceptable.
