Graduate (base model) has stamped steel wheels with dollar sized holes around the outside of the rim - if I remember right (and vinyl top and seats sometimes). and... The Quadrifoglio (top-o-the-line model) has alloy "rotary phone dial" wheels, and a hardtop, and ground effects, and more electronics to go wrong.
I want a hardtop for this one eventually.
The Veloce is the middle model. Power windows and mirrors, and alloy cromodora wheels, cloth top, leather seats.
They all had the same engine.
BTW, Doc... International Auto Parts (and maybe Centerline) sells Cromodoras new. So they're not that rare.
