I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Cesar zamora was especially helpful, patiently answering all my questions and guiding me through the options without any pressure. The entire process was smooth and transparent, and I drove away feeling confident in my purchase. I highly recommend Napleton's Valley Hyundai to anyone in the market for a used or new vehicle!

Liz in sales was always helpful and made the buying process a breeze. She addressed all my concerns about the Carfax report, pricing & extra keys. The dealership's facilities are convenient & very clean. The vehicle itself was in great condition. The financing process can be made more transparent. It would be helpful to know about the extended warranty options beforehand as cost of these options can add 10-20% to the cost of the car. It is hard to make this decision at the last moment. However, I could have added to the financing.
