With a SOHC 88hp 4-cyl engine, it's grossly underpower with A/C on or fully-loaded. Not recommended if you live anywhere with mountains in sight (my place have the Rockies)! Fine with normal around town driving or if you never go above the speed limit though.
As it's only a re-skinned Mazda 323/Protege, the mechanicals are typically reliable.
All around visibility is not as bad as you think despite the thick B-pillar. Actually feels easier than my 2002 Civic Coupe Si.
The trunk is large! It's a mini-puzzle, but I can stuff two full-size bikes (with front wheels off) in it and still close the hatch! Quite a surprise for a small hatch back.
Average on gas - comparable to engines of similar sizes.
Winter driving is OK. Just like everyone else not on snow tires.
Considering MX-3 has been out of production for a quite a while, get a V6 if you are looking for one. The extra cost is well worth it.
