florida cars 2001 inc knowingly gave me a bad vehicle miramar, Florida

On August 7 2012 I purchase a vehicle from Florida cars 2001 inc. it was an 'as is' car so felt a little hesitant to buy it but I was assure by the dealer that it was a very good car, so i decided to trade in my ford 2001 mustang which i was paying monthly with them and had a remaining estimated balance of 700$. here's where things got fishy when I traded in my vehicle they told me to lie and tell the loan people (west lake financial) i gave cash and i also notice they put on my credit application under current employer: millennium consulaton and under salary:1,600$ when I clearly told them over the phone that I make about 6 to 7 hundred biweekly and that I'm a security guard for millennium protection services they told me don't worry about that its just so I can get approve after that was done with.    

 I drove off with the vehicle and by day 2 it started to overheat as I made my way down to the dealership for maintenance that they promised me. [continued below]....

..... when i got there I mention the car was overheating barry told me don't worry about it they will take care of me and promise they would get the problem fix after they had their mechanic take a look at it.the mechanic then said it was the fan and it wasn't kicking in at times so they change it and gave me a another one and as i was driving it on my way to work it started to overheat again so i brought it back on day 3 when i got to the office they told me why haven't I
been picking up my phone and that the loan people have been trying to get a hold of me I told them that my phone was off and it would be back on Friday. it seem like they were rushing me to get it finalize with west lake financial i told them what about the car that's overheating on me they told the same old thing,that they would fix it just talk to the loan people to verify my identity i told them i wouldn't till the car get fix. they told me, and by they i mean barry the owner and one of his employee in the room at the time, that if I don't call them in time i would loose both cars and not to worry were gonna fix the problem they took the bmw key and had their mechanic check it out and told me to call the loan people so i told them let me use the phone so i can call them barry told me i cant call them on the dealer phone and insist on paying my phone bill with one of his business credit card I didn't thank anything of it i just thought he was being nice but now looking back i
realize he was just in a hurry to get rid of a bad car.

so after awards he then told me to lie to the loan people about why they couldn't get in touch with me and not to let them know i was in the dealership,I found it weird that he told me to do that when he in fact he told me the loan was already approve but still i went along with it so i then call west lake and told them whatever scripted lie he told me to tell them at the
time west lake financial then told me to hang up so they can call me so i hung up and and a few seconds later i got a call back and as they were asking me question they then ask whats my occupation i told them security guard very low and one of barry employees quickly told me to say millennium consultant which i kept saying very low to customer service and kept ask me to repeat it but because i wasnt to happy about lying i had a very low tone if you ask westlake fanancial for voice recordings you will see what i mean they then ask me about the car and ask if it was in working order i told yes but it keeps overheating and
that the dealer ship promise to fix it,after getting off the phone with them.i went back to talking about the overheating issue with barry he told me its the radiator and that he is getting me a new one and after replacing the part i drove off the same thing happen later in the day so i brought it back and that's when his tone started to change threaten to repo the car and told me i had to pay the remaining balance on the mustang or he wont fix it i went over there like 13xs trying to get this
