Reneging on deal

Reviewed by KUHLMAMA in SIOUX CITY. IOWAOctober 04, 2020

Dealer refused to follow through with the "In and Out" process when a friend purchased a new car. My friend specified during the negotiations on the new car that I would be buying her trade-in for the price the dealership was giving her for the trade-in. When I confronted the salesman I was given various excuses why the dealership was now going to charge me $7000.00 more than what was given for the trade-in. A great example of greed.

We live out of town and had our Kia serviced with Billion! Quin is very helpful and accommodating! We felt we could trust them fixing our vehicle and we were always up to date with our repairs! 10/10 love going to these guys! Its well worth our drive! Plan on buying a car in the near future from them as well!

I recently needed my Kia Sportage foxes under warranty, Quin helped with my vehicle and went above and beyond to make sure they could get the part in a timely manner. He was amazing and I would highly recommend him for service or even purchasing a car!
