Funny... when I had seat time in a Mazda3 last year, I felt that they weren't quite as sharp as the Protege... heavier, sloppier, slower.
But after driving a basic Mazda3 for a week two months ago (small engine, automatic tranny, craptastic Goodyear Eagle NCT5s), I've changed my tune. I'd count it as 50:50, either way.
Mazda did an exceptional job on the chassis. There's less steering feel than in the Protege, and it still feels heavier on turn-in, but there's less mid-corner understeer, and the whole car feels more substantial and composed than the Proty ever did. I still don't like the fact that it doesn't feel as light on its feet or as nimble, but the suspension feels so keyed in, it's almost forgiveable.
The only thing wrong with new Mazdas is the weight. Sure, the electric power steering may leave something to be desired compared to the old racks, but even BMW have fallen prey to this problem.
Besides... having owned a 626 and having driven a Mazda6, I can tell you right off I'd rather drive the latter than the former... the 626 was a fine car, but the Mazda6 makes it feel like total crap... :lol:
