spanos imports bad repair Daytona beach Florida

I bought a mercedes benzR350 at spanos on December of 2013 ,they had to keep the car because it was having trouble starting I should see a red flag when they keep saying I should come and pickup the car then I would be on my way to the dealer and then I would recieve a call to tell the problem was not fix to come another day ,that happen a few times until they finally delivered the car and was assure that they fix the problem ,all I'm saying aren't these people should have fix the car before they put it in their inventory and showroom for sale.a couple day after they delivered the car to me I went to take my kids to school and the car would not start I call them and they told me to bring the car in for them to check it out they did or they say they check it and didn't see anything wrong with the .but couple days after taking it back home it did the same thing it would not start but after you leaved it for about 20 min it would fired up like there was nothing ,I have to say that was part of my routine turn it on about 15to20 minutes before I go out so I won't make be late to wher I was going until a couple weeks after then it would not start period,I had to flatbed it to my mechanic and he discovered that who ever repair it at spanos did a very poor or didn't do nothing at all .Spanos had rigged up the gas put instead they put a new gas pump they had their mechanic  repair it by putting a whole bunch of thick black industrial blue to fix the problem but that's not all that happen it broke down again a week or two after ,so I called the manufacturer and they paid for me to take it to the dealership in daytona bch and that when they found out that spanos instead of fixing the car properly they had there mechanic re route a lot of wiring and stuff that was suppose to be in the car mark thou they had sold me the car way above market value so now I haven't driven that car about seven month and I have to pay the payments while spanos laugh all the way to the bank  at the mercedes they its one of the bangup job they had ever seen if spanos gonna sell these car don't he think the ethical thing to do is make sure he fixes these car that innocent consumers  buys from him instead of thing how do I get these sucker to come in and buy these lemon without me have to properly fixing the problem  hes no better than Bernie mad off thief in disguise
