Very rare, top of the model line 1970 Bonneville convertible, rare high-compression 455 - - first year for the Pontiac 455 and the only year for the high-power, high-compression 455 engine. I bought it in 1983, and stored it inside a new building in 1984. Has been run occasionally, motor has set up but not that long ago. No bearing problems or knocks when it was running. Very fast, nearly 400 hp. from the factory. I have about 60 antique cars and this is the last convertible. Great interior, original, no rips, good dash, no cracks. Original paint. Frame and floor pans SOLID.
