3000 GT differences

Hello;
 
 I was wondering what the differences are between the cars through the years of production.
 
 Anything from engine, trans, to the options, and colors offered.
 
I am mostly wondering about the 94 3000 GT VR4, as to what it has and don''t have that would make it better or worse than other years.
 
Thanks
