And you can also break it down farther , 90 -93 = M1
94 -97 =M1.5
98 -00 =M2
01 -05 =M2.5
Sorry but I don't like the new NC or M3 or whatever they call the new RX8 look alike , OMFG have youse seen how big the door handles are on the outside of that body stlye forgetaboutit I just don't like them and the stock wheels are way to big and the ride is way to smooth , not miata like at all , sorry but I just don't care for the NC , hell I have trouble with 01 and up .
If Mazda isn't careful they'll do to the maiat what nissan did to the 240Z , a big fat girly car , ewwwwwwwwww
