Why would I like a car that doesn't have airbags, A/C, Bluetooth, power windows, heated seats, etc.?
The exhilaration of driving something in which you can feel the road, feel the speed, hear the roar of the engine.
It's no longer just a vehicle for transportation. It used to be.
It's something different now. Love it for that difference. Enjoy it for that kind of experience.
If that's not your kind of thing, that's cool. Buy it and give it to me.
Oh, and my 1971 Chrysler New Yorker has A/C, power windows, power seat, power locks, power steering, power brakes with front discs. All factory. The AM 8-track radio with a power antenna doesn't have Bluetooth but I can toss a Bluetooth speaker on the dash or seat and cover that base. Or I could upgrade the guts and have Bluetooth, AM/FM, MP3 Aux port all in the original radio housing and faceplate.
My 1969 Dodge Charger has factory A/C, power windows, power steering, power brakes with front discs, AM/FM radio, 6-way adjustable seat (but not power).
So, the lux options are not excluded from the cars of this era and there a lot of reasonable ways to get some added in without changing the aesthetics in any obnoxious manner.
The airbags: well not even an option back then. Hell, shoulder belts were optional and they detach.
