I had previously dealt with Daytona Toyota in 2021 and already had nothing but praise from my experience then. This latest experience, however, has truly raised the bar. Tom and Russ were more than accommodating and worked not one but two miracles for me in a time of need. Thank you so much Daytona Toyota for working with me and truly making this a memorable buying experience. Despite being more than two hours away, I will be doing all of my future Toyota purchasing at this dealership!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Rex is outstanding.
Rex is outstanding. He recently sold me a new 2025 CR-V. He was very helpful and genuinely warm and friendly. He arranged for me to drive it home to see if my handicapped husband could get in and out of it easily. It was perfect and I purchased the car. After driving it for a month, I became concerned of a possible steering issue and notified Rex. He immediately fit me in to repair and couldn't have been more accommodating. Fortunately, there was no issue after all. He installed my new plates, checked my windshield washer system, and off I went...a very satisfied and happy customer. ---Karen Gingrich, Dripping Springs

Budd Baer was one of the best experiences that I ever had
Budd Baer was one of the best experiences that I ever had at a car dealership. Too bad they are so far away. Highly recommended. They were excellent working with me on our deal. They were not pushy. They took time to discuss and understand my situation. Great great people. I'm sure that you will love your experience too.

I want to thank TYLER in the collision center.
I want to thank TYLER in the collision center. I came in today afraid something might have to be painted. Instead….he was kind enough to fix the problem with a lot of “elbow grease” and quality time in solving my problem. Not only did he help me, he did it with an attitude that you don’t find much of any more. He was kind, considerate, and a pleasure to be around. Please make sure TYLER knows that although this kind of service is rare anymore, he was certainly appreciated by me and should be recognized!!
