I had an old Signet, which is a Dart derivative. I believe Plymouth made the Signet. It was a pile of junk after I drove it to college for four years. Wasn’t worth anything as it was so rusted out it would’ve cost a small fortune to get somebody to weld it properly. My friends and I decided to take it out and kill it. We drained the radiator, and the motor oil. We drove it around for hours and hours. After a couple of nights we gave up trying to kill it. The junk guy took it, and called me up later on that day and asked me if I knew that the oil plug was missing out of the oil pan. They don’t make many better engines than the old slant 6, 225.
Signet was a type of Plymouth Valiant
