Bobert -

If it didn't oversteer you just weren't goin' fast enough.

(Unless it's a Studebaker, in which case if it did oversteer you were goin' much, much, much too fast.)

Any car understeers at low speed, and will try to straighten out if you turn loose of the steering wheel.

Any car will oversteer in a turn of a given radius if you're going fast enough, and will "tuck into" the turn if you turn loose.

What separates "sluggish" from "maneuverable" is the oversteer transition speed where it swaps modes. If you're going to be a competent (and safe) driver, you need to know where that happens - for the car you're driving; and about the only way to have it not happen is to stick to unicycles.

Compared to quite a few dinky cars today, even the Corvair was a little on the sluggish side, but it was somewhat more responsive in the handling department than the average heap of its time. It seems that the majority of the designers of it's era believed that if the nose plowed in hard enough on the turns it would scare the s***t out of the idiots so they'd slow down to where it was safer to be on the road with them.
