This was the worst visit with Dalton and although my second vehicle purchase, my credit was at 813, 3 years later , I have had 3 deaths in my family and 4 in my son-in-laws. Things happen but the treat second vehicle purchase, my credit was at 813, 3 years later , I have had 3 deaths in my family and 4 in my son-in-laws. Things happen but the treatement I received was horrific. I ended up purchasing my car because it was on a lease - the windshield has a crack in it. and Marc did not offer to fix it; the car needed tires, so I purchsed them and had them add it to the bill. Marc showed me paperwork that the interest would be at 14%, which was ridiculously high, but now that I see the statement, it is at 20.9%. As mentioned previously, this was a "great deal" for Hyundai, but a terrible one for me, with Zero Loyalty, Zero discount and additional $200 monthly increase on my monthly bill. As I said, I wll be escalating this ridiculous purchase, not only on social media, but to the television stations to see what abuse really comes from your division More

Dalton will try to sell you a used car as new. Literally attempted to switch a new car with a demo car and say it was the same car. Then after you negotiate a price when you go to financing it som Literally attempted to switch a new car with a demo car and say it was the same car. Then after you negotiate a price when you go to financing it some how changes to a higher price. Absolutely unscrupulous dealer. More
