Point to consider is what a base Camaro is today. Mear mortals can't buy the COPO cars. GM must select you.
The base model is $23k MSRP (can be had for under $20k if you shop around). 323 HP per new tighter SAE standard (about 360HP in 1969 SAE).
30 mpg highway, IRS, 4 wheel disc, runs on 87 octane. 6-sp MANual with torsen style posi.
Allowing for inflation, the price went down, the features went up, the HP went up, and mileage went up.
