I purchased a Rav 4 with salesman, Garrett back in 2023.
I purchased a Rav 4 with salesman, Garrett back in 2023. He was a joy to work with. So much so, that I nicknamed my car Mr. G. Since my car is serviced there, I have an excellent rapport with my service advisor, Joshua V. His friendly, courteous, and professional demeanor embodies what it means to provide top-notch customer service. Garrett returned to his home state of Minnesota so, Joshua recommended and introduced me to David Garza, Jr. Not only was J.R. professional, knowledgeable, and friendly, but he also has an infectious energy, a genuine warmth that radiates and a commitment to the satisfaction of the customer this visible in each smile and gesture. I had my heart set on a particular color. Unfortunately, it was not on site. J.R. introduced me to the Floor Manager, Cory Boswell, who searched for the Rav 4 color and upgrades I was looking for until he found exactly what I wanted. Cory kept on checking in on me to ensure everything was perfect. My day ended with Rene Cantu in finance, who crunched the numbers, factoring in a trade-in value that was satisfactory and brought it all together within my budget. A few days later, J.R. called to let me know my Rav 4 XLE Premium was at the dealership. J.R. added that extra touch by placing a colorful bow on my dream car!!! Huge heartfelt shout-out to the amazing staff at North Park Toyota. “You guys rock!” Josie WR
READ PLEASE I love my Terrain.
READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

A "visitor" to Naples with an unexpected maintenance and
A "visitor" to Naples with an unexpected maintenance and repair situation (that could have turned into a real dilemma for me) went as smoothly as possible due to the professional and and courteous behavior of the team at Tamiami Hyundai. Josh at the front desk "settled my nerves" and kept me aware of the work and timeframe necessary. I feel now, I have a "personal" Hyundai dealership with first class service at my disposal, when I regularly visit Naples.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

David Scott Lee GMC is the best in the Biz. I have owned 6 GMC yukons over the past 20 years and the last 3 I have purchased from Scott Lee GMC. They have the highest level of customer service that I have ever experienced with any of the dealerships that I have worked with. They are my lifetime GMC dealership.

Greenway Kia North serviced my 2022 Kia Telluride on
Greenway Kia North serviced my 2022 Kia Telluride on 9/12/25. The service tech registered my car as soon as I arrived at 7:50 am. After waiting an hour, Kia provided a shuttle to take me home. When the service was completed, Kia called, and I order the shuttle. After waiting for the cashier to come, I paid what I thought was a reasonable bill. But no one bothered to inform me if the recalled power seat switch was fixed or part ordered or what. One air pressure sensor has been alarming regularly for the past three months, but the tech could not get it to alarm during the service - so, I will just have to put up with it. Kia North is a nice place, and the staff is friendly enough but were not real informative in my case.

I have bought my last few Subarus from this dealership
I have bought my last few Subarus from this dealership even though it is further from my home than at least 3 other Subaru dealers. They always seem willing to make me a nice deal on a new car, and they go above and beyond making the the process fast and convenient. Further, the sales representative with whom I worked, Reid Stanley, was accommodating, calm, not pushy, helpful and informative. Really everything one would wish for in a sales associate.
