Can I Sue The Place I Bought My Car For Not Disclosing It Was An R-title Car?

I'm in PA. I'm financing a car, and started my loan in July last year. I did this by myself, and it was my first time financing a car. My dad's a mechanic. This year we began contact again, and a few weeks ago he inspected my car for me. He found out that my car is an R-title car. It had a major accident in May last year which resulted in the insurance company qualifying the car as a "total loss" and they fixed it up, and sold it to me in July. They never once disclosed this to me, and nothing states this in my paperwork. I went over this with a lady in my dad's office who deals with financing the cars at his work.

She told me to call my financing company, whom she's dealt with & knows does NOT finance r-title cars. She told me to call & ask if they finance r-tital cars. To which I was told no they do not.

So essentially I was told something illegal happened. Whether the place I bought my car from lied to my finance company, or my finance company took some extra cash to ignore this.

I'm paying 19,000 on this car in the duration of a 4 year loan. I put down 2500, and have paid 400 each month since September. My dad stated this car is worth 2300 at most. I will have extreme trouble trading it in, or selling it once my loan is done.

My question here is, do I get a lawyer? & If so what kind of lawyer?
