Vintage Cars: t top calais, cutlass supreme, hurst olds

Question
I have a 79 black t top 4 speed calais but cant find any info regarding value rareness ect it is a 3o5 car so its not a hurst olds any info will be appreciated


Answer
Yeah, this would be a tough car to find info on.  The Cutlass Supreme was incredibly popular then, the best-selling model in America.  But it's just not old enough or "classic" enough for clubs or websites to support it.  The Calais was relatively rare, though (the top "sports-luxury" model in the Cutlass Supreme family at the time), and the 4-speed makes it EXTREMELY rare.  The 305 was the most popular motor, and many had the T-tops, but a 4-speed manual was practically unheard of in ANY mid-size GM car after 1972.
