It depends on what your criteria for "any good" are. Most cars that have depreciated rapidly do so because their maintenance burden is high. If you think you have a better-than-average ability to absorb or mitigate this risk, then it might be a wise purchase. If you cannot, it is probably an unwise purchase.
If you're mechanically inclined and have a place to do the work, pretty much any old American (due to parts availability) car is "good enough." Buying your own tools is almost always far less expensive than going to a mechanic. Time is the real cost!
It's easier now than it has been to learn how to keep cars running.
