used car rip off

I purchased a 1992 Mazda 929 from Lamb Car Company on 06/29/99,for
the amount of $9995,00 and put $3000.00.On my why home I tried to
turn on the so called $2000.00 (I was told), stero system on and it
did not work.Come to find out neither did the back windows along
with several other things.During the course of buying the car IU had
told the car salesman that I was going on vacation to Sacramento,
which I did. After returning home , I went immediately back to the
car place and informed them that I did not want the car. At this
time the salesman, whos name is Frank, told me that I could exchange
the car for another car as soon as the Fineice company got a clear
title. I asked him how long this would take and he said about 5 to
10 days and he said he would call me as soon as it cleared. I did
not hear from him so I went back in again, at this time he had one
of the lot boys take the car down to the smog place and had it
smogged. He then told me the same thing that he told me the first
time. They need a clear title. I waited again and then went down
again/. I told Frank that I was worried about the time that was
passing by, he said "don't worry about that, we don't care about
that." I had explained to him that all these things did not work on
the car and that I believe the car has either been in a flood
because I have mold growing on the head liner, corroded electrical
parts and that it smelled like mold everytime you turn the
air-conditioner on. I am also having problems with the brake light
alway being on,too. Now, for the passed 3 weeks I have been trying
to get ahold of Frank and he never there so finally I went down and
spoke to a man who wrote up the contact, Zack, and the next day I
called there several times and spoke to Frank. He said he could
trade the car for another if I wanted but I would lose my down
payment and I would have to pay tax and license again. The tax and
license I will pay but not my 3,000. dollar down payment. Have they
done anything that I coulsd have any recourse on to get my down
payment back?
