Very pleased with the handling of the sale.
Very pleased with the handling of the sale. Almost no wait time. I did notice on the envelope for the paperwork, that the address of the DMV is incorrect. It, the DMV, is on Zumbhel now not on Raymond.
2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Great Dealership
I walked in with a budget and specifics of what I was looking for. Curt found me the perfect car above my expectations and 400.00 under my budget. I highly recommend Bommarito Nissan.
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.

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!
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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

Joe is great as well as all the people I interacted with at the dealership. They all were very friendly and professional. I appreciate Joe getting me the best deal possible with this being a second car loan.
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!

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.
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

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.

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

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.

Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.
