Had a naturally aspirated Mk3, was OK, very comfortable and they drive quite sweetly if they've been looked after. Hard to find an unmolested version these days and most are full of rust.
If there's no history, it'll need a new headgasket, uprated bolts and the correct torque setting for those bolts at some point. Toyota issued the wrong specifications for the head bolts so the headgasket can go with ease, if you're unfortunate.
Only real bugbear I had with mine was that it was lowered too much so tended to snag on everything.
Not particularly practical or slow, though
. Rear seats are really only for short people, or trips.
Other than that, as mentioned, rust rust rust! Even clean ones can be absolutely full of it underneath, especially main chassis rails and rear strut towers. Get the carpets up or really get your head underneath with a good torch.
