2020 NISSAN ROGUE
This is car number 8 with Midway Dodge. This is the only place we shop. We always receive great service from everyone here. Thank you for the great service especially Money Carlos
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Great buying experience!
Recently bought a beautiful 2018 Sienna from this dealership! I can't believe that got approved for financing, after going to 3 other dealerships and everyone turned me down, saying that I have two many cars under my name already! Honestly when I got here I still had in my mind that getting approved is impossible, but Andrei did such a great job! He really knows financing and how to take care of people! I recommend them to everyone!
