I have never felt more comfortable in a dealership. They have the most professional staff in the business. You can tell the employees and customers are truly valued here. Finance manager Danny Daher is the most professional ever

Bought A 2015 Mini Cooper from John at Lee Auto Group and he went over and above to take care of me He noticed a small noise and replaced the accessory belt. there was also a problem with charging and had it repaired by the qualified and professional mechanics by staying late and in no time had it repaired. I live near Ocala and he even offered to drive me home if I needed it and called to make sure I arrived safe can't expressed the service I got from this amazing company I would absolutely recommend them to anyone. Again John Thank You ,Richard

Excellent used car. Excellent service.
We needed to find a good quality used Honda in a short time to replace our car that was in an accident. Eric Campisi, the owner of Autoplex, drove the car to our home for us to look at and test drive. He was extremely helpful, informative and kind. He also helped us arrange financing. We bought a 2013 Honda Civic LX Sedan in very good condition and are pleased with it. Eric's willingness to bring the car to us is what made the sale, along with the high quality of the car itself. I haven't purchased a used car since I was a teenager and was a bit wary of what I might expect, but Eric made the whole transaction completely painless.
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

I was reviewing dealerships service histories to help a friend, and came upon Lakeland Hyundai and Genesis. I had previously responded to numerous Genesis surveys but never responded to cars.com or other auto website reviewers which caused me to decide to do one for Lakeland Hyundai/Genesis. I have purchased three "Genesis" from now Lakeland Genesis. The first in 2009 was a Genesis under the Hyundai brand. That was eventually traded for a 2015 Hyundai Genesis, which was eventually traded for a 2023 Genesis G80 from their new dealership location. Each newer vehicle was improved from the previous vehicle with newer technology and safety equipment. All were trouble free, very comfortable, well performing, economical vehicles. All the maintenance for all 3 vehicles over 14 years were performed by Lakeland Hyundai/Genesis. The service staff were always pleasant, and the service was performed as expected generally on a timely basis. Although there were a couple of recalls during that period, I had no mechanical problems with any of the 3 vehicles. I did however purchase the extended service plan with each vehicle for the regular maintenance. I did have a question with the recently purchased vehicle service interval of 8000 miles, but they assure me that with the newest synthetic lubricants that has become the standard oil change interval.

SUPER DOOPER CAR SERVICE
I just got home. I left my house at 7:30 this morning and was at the dealership for five hours. BUT I had asked them to do a complete assessment and they did everything. I love these people. As I drove up my little four legged service person got all excited. She knew where we were and she has a lot of friends there. Everybody came out to greet us and help us descend. As a rule I am treated as someone special. I'm not but I am 87 years old and they are careful to take good care of me. I know them all but am losing my ability to remember names so please forgive me guys but Roderick, Arsenio, Luis, Denisa are so kind and I wrote down their names so I could remember them. My car was very happy and I don't know what all they did but she was very happy. (Yah! She's a lady). I have a very serious suggestion: Now I have no intention of ever buying another car , BUT, wouldn't it be great if you could go to a dealership, (as a woman not knowing much), and find a salesperson there, (of the female persuasion) who not only knows cars but knows the mechanics and has been taught the correct way to sell? I would scout places that teach car mechanics and see if a female is part of the student body and offer her a course in selling and a job. Maybe she just wants to be a mechanic but you could still call on her when you have a woman to sell to. Just an old lady's idea. I encountered a super female salesperson at a Honda dealership in Kissimmee, FL about 25 years ago. The only reason I didn't buy her car right then and there was I had decided I wanted a Chrysler. Anyway, You guys get all the stars. I know i can trust you.

I recently sold my car to AutoNation Ford, and it was a wonderful, smooth, and completely hassle-free experience. I would especially like to thank Edward Mowery, who handled everything in a very professional, transparent, and respectful manner. Edward clearly explained each step, offered a fair and straightforward deal, and made the entire process easy and stress-free. There was no pressure at any point, and the transaction was completed efficiently. I truly appreciate the honesty and customer-focused approach shown by Edward and the AutoNation Ford team. I highly recommend AutoNation Ford ? and Edward Mowery in particular ? to anyone looking to sell or buy a vehicle with confidence. Thank you for a great experience!
