How many days or hours do you have to return a used car in Florida after purchase?

I purchased a vehicle 02/04/2014 from Nimnight Buick. I and my Uncle was told by the sale consultant Thomas that I would get a service called First Place Finish for free under warranty but when I reviewed the purchase information when I got home last night I have a fee of 299.95. Moreover, Florida law new tire fee per tire is $1.00 but I was charged $5.00. Third, the lemon law- warranty enforcement act states for new cars only but I was charged $2.00. I also informed Thomas that I wanted to transfer my tag and registration to the car I purchased but X is marked on new instead of Transfer. I've been charged $150.00 for Florida Title, Registration and license fees as new. I did not realize these charges until I got home. In the process of me purchasing the vehicle I told Thomas I was financing the car through my bank, and I he said they are partnered with VyStar and can complete the financing with their financial department. Unsure about this.
