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.
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

Dear Honda Management, We would like to thank you for your outstanding service staff.

Your continued selection and development of top-notch individuals like them is what sets the Brandon Honda dealership above all others.

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 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!
