Your title says you're looking for a RAIV Firebird. I believe there were a total of 105 auto and manual RA IV's produced that year making these more rare than Trans Am Ram Air cars. I believe only 85 coupes and 20 vert RAIV Firebirds were produced in 69 making the RAIV Firebird a true unicorn only in comparison to a Trans Am vert as far as pricing and rarity.
Last Firebird RAIV I saw on auction sold for well into the 160s.
He did say he was looking for a needle.
