Got the car I wanted at the Price that I could not pass
Got the car I wanted at the Price that I could not pass up. Ivan was very easy to work with thank you very much for getting me the car that I’ve always wanted. I drove an hour and a half and it was well worth the trip.
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!

I was very pleased with my recent car purchase experience
I was very pleased with my recent car purchase experience at Legends Honda. Dylan Lett, Gregory and Lauren were most helpful providing me all of the information I needed to trade my car in and buy the new car that was right for me. Thanks for your most professional, informational and courteous assistance. I will be recommending Legends Honda to all of my family and friends who are planning to sell trade or buy a new car. The service department provided great service also. Great Job!!!
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.

Fantastic dealership.
Fantastic dealership. They worked with me and dealt with every curveball from credit issues to simple communication problems without skipping a beat. Got the truck I wanted at a great price, better than just about every dealer in the region. Even helped me turn in my rental and detailed the truck before driving it off the lot, and gave me a gas card for some extra drive time, DESPITE the dealership having been closed for the day when the deal was done. You could tell their priority was getting me a vehicle I was happy with, not making a sale, which was a huge relief. Personable staff, honest dealing. Would recommend them any day of the week!
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

I've dealt with better.
I've dealt with better. Not completely negative of an experience. Not the best either. Their service dept seems to be slacking. How do you put a car on a lot for sale with a check engine light on? I can see when it was last cleared. Not very long before I bought it. Salesman trying to tell me the engine isn't getting up to temp because it's cold outside. No. It's a bad thermostat. Headlight wasn't plugged in. And WAAAAY out of alignment. Their cars are supposedly looked over with a xx point safety check. I doubt that. Looked over, cleared codes, topped up fluids. Put an oil change sticker on the window. But did they really? It looks clean so I assume so. The detailers did a FANTASTIC job!! This car was super clean!!

Had an amazing experience. Completely different from anywhere else I've been. The staff was genuinely helpful, not pushy, and made the whole process smooth and stress free. They took the time to understand what I needed and went above and beyond to make it happen. Highly recommend if you're looking for a dealership that actually cares!

Purchasing my Truck from JKB Auto was a pleasure.
Purchasing my Truck from JKB Auto was a pleasure. This was a first for me, buying a vehicle online, might I add that this was most pleasant experience ever buying a vehicle. From Samantha to Nick and Robert- who was excellent in explaining all that was required of me to finalize this deal from long distance(Louisiana). The Dodge Ram 2500 was exactly what I was looking for in a truck. Great truck runs fantastic and the pulling power is amazing. If I’m ever in need of another vehicle I will definitely call the folks at JKB Auto.
