For Two - Smart Car a bright decision
Eric and Tiffany took very good care of me. The entire process with Eric was smooth and so easy. Eric was responsive to any question via email, phone and in person - he talked to me like a normal person and that was nice. No push, no rush to buy, very carefully handled by the team.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Sports Honda did a great job finding the exact vehicle
Sports Honda did a great job finding the exact vehicle that I wanted even going to another dealership to get it. I bought it through Costco‘s membership and it was Hassell free. Not all dealerships participate in this program, but I was glad sports Honda did. Alex Molina was great to deal and he obtained the car from a different state in the same day. It was also very easy to work with Josue who arranged the financing.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.
