That looks like the 77 and later ones. I sold a complete set....elbow and wheelhouse duct, plus the bracket for $30 about a year ago to a forum member. If prices keep going up, new enthusiasts like Tommy won't be able to afford the hobby.
I saw a drop dead gorgeous 1957 chevy bel air convertible this week. Black with red interior and a white top. The guy paid $70K for the car and has put another $16K into it....and isn't done. None of what he's done is body work or paint...just mechanical stuff. Who can afford something like that? He did pay too much for it though.
I also saw a 1967 Mustang fastback that had a frame off restoration. The car looked like it just came off the assembly line. He did his homework and did everything like the factory...from paint to the correct bolts and stickers...he put $50K in the car. My friend bought it for $17K...the deal of the century.
I hope the Trans Am's stay in the world of affordability for at least another decade.
