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!

Great experience
I have purchased several vehicles through LMD over the last several years. The process has always been quick and painless. We enjoy working with the sales manager, Isaac and Joel in Finance. Highly recommend!
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.

Best dealership in the United States!
If it were possible to add stars, in this case, I would do so. From great communication, to incredible follow up, to providing vehicles that exceed their descriptions, this dealership is incredible. I must commend Keith in particular. He was/is always willing to take time to take care of his customers. He knows his products. He gets to know you (the customer). Just a great guy who is wonderful to work with. Look at the other reviews of this company. They are all consistent. And there is a reason for that. You will also have a stellar experience when choosing 101 Motors!
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!

Overall positive experience.
Overall positive experience. I found the truck online, and when I got to the dealership the pictures were accurate of condition. Worked with John, let me drive the car wherever I wanted (other dealers only had predetermined routes and they sat in the back). Had 1 concern about the truck, which John handled before I came back the next day to bring my trade in. Buying process was straight forward, and no hard-ball tactics.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Great experience!
I purchased my Grand Cherokee from Matt Sarnocinski at Airpark Jeep and I couldn't have asked for a better experience. No games, no back and forth, just right to business. Had me in and out in about 2 hours. 10/10 would recommend!

I'll be so honest, I hate car shopping (like most people do). I ventured to roughly 6 or 7 dealerships in the valley within the past few weeks, but ultimately I'm really glad I gave Arrowhead Honda a shot. I want to give a HUGE shoutout to Bryson for going the extra mile! Bryson took his time answering all my (many) inspection questions and was super patient while I made my decision. You can tell he extremely knowledgeable and passionate when it comes to cars, which isn’t something I've seen with most salespeople. At the end of the day, Bryson went above and beyond in making sure I felt totally comfortable and confident with my purchase. Thank you for a great experience!!

My lease was up on a few months and this particular
My lease was up on a few months and this particular morning when I was driving to work there was a loud grinding noise coming from under my truck. So, I called Ashley in service and told her I would be bringing my truck in this afternoon. As always she greeted me with a big smile. When I explained the issue and about my lease being up soon, she introduced me to Adrian. From that moment he had everything under control. He asked me what I was looking for and what I was willing to pay. He spoke to a service writer, came out with numbers I was happy with, showed me a truck I asked for and the deal was done! Adrian went above and beyond. from the storage boxes under the rear seats to the safe in the center console. He even cut off my trailer hitch lock on Saturday for me. I Adrian and Ashley a 10+!!! GREAT JOB!

Actually not a bad place to buy a car.
Actually not a bad place to buy a car. I mean, it’s still a car dealership and the usual shenanigans apply, but they will negotiate, and they’re civil and professional. And they give you top for your trade, as I’ve shopped 4 other dealers, they were the best by thousands. Management does a good job too. Frank in particular is a good TO guy. All in all, if they have the car you want, buy from them. You probably won’t do better anywhere else

Excellent New Car Purchase
We bought a new 2020 GMC Terrain from Bill Beaudry. He made the process incredibly easy, even with us living in Tucson. He did not pressure us to come in for a trade-in appraisal before giving us his best number. He promised to make us the best deal - and he definitely kept that promise (his numbers were several hundred less than any other dealership and THOUSANDS less than Tucson GM dealerships). We were in and out of the dealership in less than two hours total. Bill is extremely patient and answered all my crazy questions/concerns. He was even able to find a Terrain in a different color after I realized my fiancée NEEDED a white one. The finance representative was low-pressure and did not coerce us into any additional extended warranties, etc.
