Wonderful Car Purchase Experience!
The sales team members were so eager to help make my car purchase an enjoyable experience! Diana, the Internet Sales Specialist, was very friendly and helpful. She helped coordinate everything with the sales team perfectly! They sent videos of the car I liked. They were very friendly when I had the car inspected by an independent mechanic. When we agreed on a fair price, the sales manager delivered my new car and took my trade-in car back to the dealership! We completed the paperwork in five minutes at my home. It was such an easy and enjoyable purchase experience. I contacted several Nissan dealerships in the area and Hawk Nissan was the absolute best!! I would highly recommend this dealership!
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

This is our ninth Ford and our eighth from Packey Web.
This is our ninth Ford and our eighth from Packey Web. We have dealt with the same salesperson each time. Elliott Sivewright has always been awesome every time. He knows us now, so this last transaction was a breeze. We called him and told him what we were looking for and what amenities we absolutely wanted and what amenities we could do without. He found a couple cars and told us to come in. We left with one of those choices a few hours later. Always great service!
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Victor Riley - A+ salesman- 2nd time doing business here
Victor Riley - A+ salesman- 2nd time doing business here and I will be back again for the 3rd time. Professional, knowledgeable and not pushy. Everyone from sales to service gives top notch customer service. Highly reccomend for your next vehicle purchase.
Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.
