They are a large dealership with a very large sales volume. If they were not reputable, the state attorney would have put them out of business by now.
Because they are large, with many different sales persons, finance and insurance pushers, and low-level managers, with turnover in staff, each client's experience will be different, some happy, some not happy.
I prefer to deal with small family-owned dealerships, but then I have to deal with what is happening at one of my favorites: Pop is retiring, nobody wants to take over or buy the business, thus ongoing support from that business is now gone. But the big guys sometimes go under too, mismanaging finance or failure of their business plan to keep up with market realities.
I would not go to Tampa from out of state just to buy from them, there are too many good dealerships closer to home. But if I lived in Central or South Florida, this is one of the places where I would shop, just for the variety they will have on location.
