Quite a few cars looked like $hit in the mid 70s because someone thought the square headlights would look good on cars designed for round headlights. The Firebirds were redesigned just enough that they looked great but all I see here is opposite.
Not really my thing, but here's a new-to-me old hot rod called "T-Bucket" or "Kookie's Kar". It sold at auction in '18 for $484,000, so apparently it's famous.
