got this car about a month ago. I did a fair bit of homework, and figured I'd share the pros and cons.
2001 Mazda Protege ES GT 2.0, 5 speed.
Pros:
-lots of pep
-corners very well
-easy to keep clean
-feels sporty overall
-roomy enough for me at 6'3"
-decent fuel economy
-seats are pretty comfortable on longer trips
-have had comments from a few girls on how much they like it :-)
cons:
-seats don't seem to have enough vertical grooves. I find my back gets sweaty very fast in this car. Will probably just pop in a back rest thingy.
-cupholders are too shallow
-heat shield on bottom of car started rattling, they removed it. not a biggie, just an annoying sound, now gone.
-some owners have told me that brakes are a thing to watch. E.g., have the rear caliper sliders lubed religiously??. Though, I haven't had that done yet.
-strange steering. Not sure if this is warranted as a con really, but the steering on Proteges is different from most cars I've driven. It's hard to describe, but suffice it to say that bumps/shape of the road will pull the steering around. It's not bad, and kinda gives more direct sterring control, just odd to me. I'm used to GM cars where I can steer with my index finger if I wish :-)
Overall, very fun car to drive, quite happy to have it (so far).
