It was great working with David K.
It was great working with David K. He had a ton of information and new the santa fe and it's features very well. No pressure sales from him.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

This dealership doesn’t negotiate price.
This dealership doesn’t negotiate price. I randomly walked in one day and Michel helped me out, he sent me different car options over a few days and ultimately helped me purchase a great car. It was a quick and easy process which I appreciated and also a no pressure environment which was nice.
Love it.
I love the new features this truck offers. I would highly recommend this truck if your looking for a Diesel. I provides all the features and benefits you would want.

I love my Lexus, Maplewood has very attentive sales people. I visited 4 times and every time they treated me very well, even though the first 3 times i wasn’t buying anything. I finally found my dream car. Couldn’t be happier. Courtney my sales rep was great, she even dropped my car off after the wrap was done. I highly recommend this dealership.

Great deal from Coulter
Coulter dealerships have been very good to me with the vehicles I have bought from them in the past. Coulter Cadillac was the best experience yet. I got a great deal and I know it! The deal was mostly done on line and did not change the day the xt6 was picked up. This is not the usual dealership experience. No wonder Coulter has been around for 100 years. Thank you very much, Steve and Nancy

Cameron came to house yesterday for a mobile service, as always he was a very knowledgeable professional. He explained what was needed and most important WHY!!! Parks Ford Mobile Service is a great addition to their service dept. I would also note that Donna back in the dealership is great keeping you informed on your appointment and on the day of the appointment the ETA.
