Those mid 70's cars are a tough one for value. The Colinaide cars were made during a terrible time. Being the one year, special Can Am does make them actually valuable to a certain extent. We had our 75 Cutlass 4 door, nicknamed the beast, overall decent and gave me the respect for the SB Rocket 350, took a heck of a beating. I bought a 76 2 door Cutlass for $50, 20 years ago. I still see nice 2 door Cutlass take forever to sell at a couple of grand. They are big, not my cup of tea for styling and way underpowered. GM cars were way better than Ford or Dodge in that era, but those were plain awful. My bet is a relative died and this person inherited the hoard. I don't think a lot of parts are made for the Colinaide cars, due to their value and not being popular. A reproduction bumper wasn't available for my 76 and they all rotted out. That and getting a title made me not fix up that mint interior car, $50 car. Hopefully a Can Am person sees this and saves it.
