A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I don’t write many reviews but I felt one employee
I don’t write many reviews but I felt one employee deserved to be recognized. Celenne M, the Title Clerk. After leasing a car from another Gettel location more than two months ago, she inherited my problems. The title, tags and registration had to be transferred from another state. Additionally, I had numerous changes in paperwork to do and temporary tags to change out. It has been a frustrating situation. And took a lot of work. She constantly kept in touch with me and took care of everything without me having to contact her. This is made it could’ve been a really difficult and unhappy experience a good one. Thank you
In about 15 vehicle I had, this the best one
This truck just need nothing, comfort, strong, and beautiful, it's great for work, and for personal use, my next car will be the same but new

Both of them went above and beyond to ensure that my experience was smooth, professional, and handled with genuine care.

Their professionalism, patience, and positive attitude truly stood out, and it made a big difference. Exceptional service like theirs deserves to be acknowledged and appreciated.

I highly recommend seeing Adam Hussein if you are in the
I highly recommend seeing Adam Hussein if you are in the market for a new car. He was adamant about getting me the best deal possible on a new car. That being said, when you are ready to do the paperwork, be prepared for a subtle, continuous pressure to buy an extended warranty. I hate to confess that I caved to the pressure because I zeroed in on "10 years" and not "85,000 miles". My previous Toyotas have made it over the 130,000 mile mark with no issues that would have required an extended warranty. It's 4 days later and I'm still obsessing about agreeing to that warranty!

Excellent Service all the way around. Maintenance was completed in a very timely manner. My initial appointment wasn't until 10:30 am. As I did not have any particular things going on so dropped it off at 8:30 am and told them that they could keep it as long as necessary. I received a call at 9:30 am stating that all maintenance had been completed, an our before my scheduled appointment.

Im glad that I came across this dealership, as soon as i arrived I was greeted with profound professionalism. I had all the right answers to my questions and didn’t feel pressured nor felt like I was being hustled. I described what I was looking for and they provided me with a few different options that matched my description. They made it real easy and comfortable. I’d like to say thank you to the staff and Mr Hernandez for marking it a great and easy experience.
