I Went in to have our 2025 Tucson serviced.
I Went in to have our 2025 Tucson serviced. They were very nice and helpful. They even gave it a wash before returning it. Thank you.
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!

I have owned a Honda since 2009.
I have owned a Honda since 2009. When it was time to buy a new vehicle, I called Gerald Griffin. By phone, we had a preliminary deal for the car and price. When I walked in the door, I changed my mind about the vehicle 4 times. Mr. Griffin was extremely flexible and patient. For me, the decision to commit to purchase such an expensive item makes me anxious. Mr. Griffin did his best to help me feel comfortable and his efforts are appreciated. Did I get the vehicle that originally wanted? No, I reevaluated and chose the best for my personality and life style. Did I get the price I wanted? Yes, but the add ons pushed at the seams of my budget. I hoped to get in and out, but changing my mind resulted in spending hours at the dealership. I got the financing that I wanted. At this time, I have no regrets.
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.

Went there yesterday with a Truck in mind.
Went there yesterday with a Truck in mind. Met with Nick G at the door, he was extremely helpful and professional. He got us the truck to do a test drive -- we loved it and were able to make a great deal, including trade-in so the deal worked for both parties. I am from MA, but I'd def take the hour ride back up if they had another vehicle I was interested in!

Working with Rich Tom was an outstanding experience from start to finish. They were knowledgeable, transparent, and genuinely focused on helping me find the right truck — not just making a sale. The entire process was smooth, efficient, and pressure‑free. I’m thrilled with my new 2025 F‑150 Lariat and highly recommend Rich to anyone looking for a great buying experience.

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

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.

From the Service Deoartment to the Sales Department I
From the Service Deoartment to the Sales Department I couldn't have asked for a better experience. I was greeted by everyone that I encountered throughout the dealership. Dennis was extremely welcoming and remembered me from 2.5 years ago when i purchased my car. Dennis made the entire financing portion of the sale easy and took time to answer any and all questions I had. He never made me feel rushed. Samantha was wonderful to work with throughout the process of choosing and purchasing my new car. This is why I only purchase my vehicles from this dealership.
