jd byryder brockton ma lemon of a car brockton , Massachusetts

I bought a car from the jd byryder in Brockton Ma. I had it three days and the brakes fell off. I had it fixed by my dad who is a mechanic. I have owned this ford taurus SE exactly four months and now im paying 1200 to have an engine rebuild. i was told the the car isnt even worth 5,000 dollars with the amount of work i need to put into it. I have to pay in total 12,000 for the car to own it. This is a lemon i was sold a car that is falling apart. When i financed it the dealer gave me a speech about how every car is gone over with a fine tooth comb and nothing is missed and they would never sell anything they themselves wouldnt buy. This car has been falling apart since the day I got it!
