There are still cars out there, give you an idea I found a 1970 Sportsoof a while back for $1,000 it was a factory V8 car, disc brake car, power steering car missing just about everything.
The drake cars are great for guys building the Gone in 60 seconds cars (kind of getting old), or guys that want to do other really bad things to fastbacks. If you just want a nice clean original style car, you can find fastbacks, becuse you are talking about $24K total.
Here are just a few within 30 miles of my house.
