Owned a 71 some time ago. About what you’d expect in terms of quality from almost anything of that era. But for a weekend tinkerer and sunny day car...perfect.
On one point I’ll respectfully disagree with Nick. The later cars (74-76) are great too as the smog stuff is easily removed and most have already done so.
Have never owned a “B” but this guy has one listed that seems interesting for the $. And not terribly far away from us N. Georgians...
If we weren’t planning to move in the spring, I’d be all over this:
