1994 Rx-7 Flip Up top
 

i was wondering of all the models what are the differences between the flip up tops, moon roof, sun roof and or just a regular 3rd generation rx7 without any of these, which one is a better model

There only exists moonroof or none.

Base and R1/R2 have no moonroofs, 93 Touring (as well as 94/95 PEP IIRC) has a painted moonroof, and 94/95 Touring has a highly sought after glass moonroof. To ask which one is better is a foolish question... it all depends what you are looking for, interior, performance, etc...
