All original - including the rust. Did not know you could get column shift on the Camaro as late as 1975. https://dallas.craigslist.org/mdf/ctd/6009219093.html
I would have thought it would have been an option on the base Camaro all the way to 81. But low sales volume may have finally killed the option after 78. No under hood shots of the mighty intergraded intake/head 1bbl 250 I-6? It sure looks like about as base car as you could get, the only options I see are Automatic Trans, Vinyl top, trim rings on the base wheel & dog dish caps, and Bumper rub strips. I don't see A/C controls on the dash, and no under hood pic's you can't tell if it has Power Steering or Brakes (or A/C). Seller does not mention the options other than "Rare Combo" and the old Ebay auction number he lists that has the 150+ pictures on it did not come up for me. Heck I can't tell if the car even has tinted glass? $5000 for a rusty, low option I-6 powered automatic 75 Camaro? Good luck with the sale.
eBay link. He spends all his time in the ad talking about how great and rare and awesome it is since it's such a low production car being a "plain jane" where the next biggest car collecting craze is going to hit. Which is stupid salesman talk because anyone who is going to buy a car to collect is going to buy something NICE and NOT RUSTY, with the exception being a highly desirable car that they know they can restore for less than it brings at sale time. Manual brakes and power steering. AM mono radio, vinyl top, side moldings, and automatic are the only things it has for options. It's just a no-option basest of base model car that's pretty rusty. It was undercoated (for $15) when new, so that's probably the only thing that saved its frame rails and floors. They gave the lady $670 for her 1962 Chevrolet she traded in...
Looks like you could fit a few fingers through on the passenger side quarter panel at the bottom of the vinyl roof.
Wow the rust is much worse than I could tell on the small C/L pic's, that car did not spend its early life in the Dallas area that's for sure. I bet it came south in 1979/80 during the down time up north and the oil boom in Texas. It has as bad if not worse rust than a car that spent its entire life in Michigan.
