Mickey,This car was given to me by my aging mother in law who loved it. She didnt take car of the paint! Scratches everywhere from trash cans being dragged by it. Everything worked, except the radio...

Hello. I just got a 1995 Riviera SC with 48K miles. Nice car. I am a retired EE and just getting into this engine stuff.
