Billy was upfront and personable during the Palisade negotiations. No BS...I recommended him to my son during his Sante Fe negotiation. Billy located and brought in the vehicle he wanted.

Great location and the perfect setup, easy in and out. They know what they are doing and have state of the art equipment.
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!

Thank you Aaron Voege
My salesman Aaron Voege was excellent,courteous and I will recommend him to all my friends.. He made the transition from my Altima to my new Rogue perfect. Thank you Aaron..
Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Leasing a 2021 Tiguan
I’ve driven Volkswagens since 2002. My very recent leasing experience was seamless thanks to Jason K. The Bommarito team was informative, efficient, and pleasant to work with from start to finish. Thank you, Jason Kresko!
I bought this after going to the dealer just to look at
I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

My wife and I bought 2 24 Grand Cherokee’s from Allyson
My wife and I bought 2 24 Grand Cherokee’s from Allyson Laws at Napleton and it was a great buying experience. We appreciate great service and great was what we go from Allyson. We were just really shopping when we contacted Allyson She worked hard to develop the sale and then close it. We were challenging customers, we were looking for unique configs, we were under a tight time line due to the desired Chrysler incentive ending and we were not local to the Dealership. Everything until signing and pick up were done by email, text of phone call. Allyson was awesome from start to finish with excellent communication skills, attention to detail and patience with us ( I almost changed my mind on what model I wanted at the last minute). She found the configs we wanted and worked hard to get them. One came from a dealer 400 miles away. She will work hard to get what you want. Again we are challenging ( Engineer and Data Scientist) we have a lot of questions and Allyson mastered each and every on everyone of them. She worked both deals simultaneously and it was flawless. Additionally the weather was absolutely terrible with snow and seriously below zero temps. I really don’t know how she pulled it off actually; I’m really impressed. Her walk through was superb and notable because it was 20 below zero that day. I would not hesitate to buy again from Allyson. I expect that in a couple of years we will go back to buy another Jeep GC and she will be running the Dealership. Allyson is top notch.

My experience at Frank Leta Honda was truly top tier from
My experience at Frank Leta Honda was truly top tier from start to finish. From the moment I walked in, I was greeted warmly, and it was immediately clear how much pride they take in their dealership. The space was spotless and thoughtfully set up to create a great customer experience. My sales associate, Cody, was exceptional. He was easy to talk to, incredibly patient, and thorough in answering all of my questions. One thing that really stood out was the way he took the time to visually explain the difference between buying and leasing…something that can feel overwhelming. He broke it down in a way that actually made sense, and I never once felt pressured. Instead, it genuinely felt like he had my best interests in mind. There was none of the typical sales pitch energy that can make car buying stressful, which I truly appreciated. Cody also went above and beyond by moving a vehicle indoors so I could look it over comfortably despite the freezing temperatures and high winds. He made sure I fully understood the deal and then walked me through the vehicle so I felt confident using everything before leaving. I also want to recognize Tito and Ray in the finance department. They made that part of the process incredibly smooth, taking the time to explain each form clearly and walking me through everything step by step. Their attention to detail was impressive. Overall, this was unlike any car-buying experience I’ve had before. I never felt rushed or treated like just another number. Every associate I worked with, from sales to finance, clearly cared about delivering exceptional service. I can’t recommend Frank Leta Honda enough.

Not super high pressure sales process
Had car salesman Hunter that was extremely helpful in finding a used SUV for my price range. Showed huge variety and among a variety of brands and even let us drive home to see if it'd fit in garage no problem. Price was acceptable and car we got was great! Highly recommend Hunter as salesman as he was more than accommodating to get the car we wanted.
Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I'm driving a new '23 4xE! Thanks Jerry Kasten
Between my Son & Daughter-In-Law and I we have leased or purchased eleven new Jeep products through Jerry Kasten and Glendale. Great deals, great service after the sale and a solid Finance Department are the reasons we keep coming back to Glendale.
2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

Great deal on a great Kona!!!!
Had such a positive experience. Luke LaFond greated me when I came in the door and spent the day working to find me the right car within my budget. He was kind and very patient. I wouldn't hesitate to contact him in 2024 to lease my next car. By the way, I could not be happier with my Kona. It is sharp looking. When going to take care of the payment, Joey also bent over backwards to make me comfortable. Pam Marquitz

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!
