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.

My experience at this dealership was nothing short of exceptional. From the moment I walked in, I felt supported and guided through every step of the process. They made it seamless, transparent, and genuinely enjoyable to purchase a vehicle. Jaguar Land Rover South Shore has earned my trust, and I won’t buy a vehicle anywhere else!

Rizza GMCCadillac see Coach
We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

I would recommend client manager/sales person Bryan Druktenis. He is very professional and friendly. He did not pressure me. Lol. Once l purchased my vehicle(s) he was very helpful in showing me how to set up my features and answered any questions l had when l called. Bryan was my sales person for my Acadia that l traded in for the Yukon.

What an amazing time I had buying my first car!
What an amazing time I had buying my first car! I believed that my time with Michael Darge was going to be hectic, but it ended up being the most relaxed and educational period of my life. Michael made this transaction enjoyable and stress free in addition to being nice and willing to teach me everything there was to know about this new car. Michael being a Marine Corps Veteran and coming from a family of veterans, Michael and the Garber Chevy staff treated me with the utmost respect. I strongly advise anyone looking to purchase a vehicle to visit Michael Darge. Thank you so much once again!

Main Street best used car dealership in Valparaiso
Amazing people, Main Street Motors is the hands down best used dealership I have ever purchased from. My car has 50,000 miles and they had brand new tires and brakes put on the vehicle with a fresh oil change. Can't say enough about the people here.
There are 20 matching cars close to your year range.
