I am a Grandmother with 12 Grandchildren and I nee
I am very satisfied with my vehicle...my salesman was very knowledgeable about the vehicle I wanted to buy...He recommended certain things and I took his advice...I am very happy
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!

It was a long 5 months (due to back ordered parts) but DeAnthony made it such a breeze. He gave me weekly updates, answered all my questions thoroughly, when I needed a rental, he got it for me with no problem and had some of the best customer service I?ve ever experienced. I will always be returning for any services my jeep may have. Your mechanics are so detailed, they made sure all issues were fixed before they released my truck. I really appreciate all of you, you guys have an awesome team! Thanks for taking care of me!
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.

Gullo Toyota of Conrow
Rob Comstock has been an excellent help to us in regards to our new car purchase (both of them). We are very pleased with our new Rav4. We cannot thank everyone at Gullo enough for helping us exchange the Prius we originally purchased (which it turned out was not the right car for us) for the Rav4. Please thank Mitch Ericson for processing our paper work twice. Also, extend our thanks to Mr. Grice who spent a great deal of time going over all the features of the Rav4. We went to Gullo because your on line customer service rating was four and a half stars. I am so glad we did. I'm not sure any other dealer would have been willing to exchange cars after purchase just to make a very short old lady feel comfortable and save while driving. I have responded to Toyota's survey and have let them know how great your dealership was to deal with. Thank you again.

Bayway Cadillac of the woodlands
After searching for a good month for a used vehicle I finally found a dealership that would work with me with my trade in value, Laurel Williams and the sales managers moved mountains for me trying to get into a vehicle I wanted. I highly recommend Bayway Cadillac of the woodlands, top notch customer service and a pain free buying experience! Thank you! I will definitely be coming back for the next vehicle purchase.
