You will be very disappointed with a non-turbo/V6 Calibra.  
Still moderately good looking cars if standard, but they do not handle well at all.  2.0 16v is a real slouch compared to the Valver.  Point to point, cross country, a 16v will murder a 2.0 Calibra.  Only a V6, turbo or 4x4 would cause any trouble.  
Different cars really, but the 16v was the best of its kind back in the day - still shows newer hot hatches where its at - just like the GT Turbo or 205 1.9 GTi do.  Calibra can hardly call on that pedigree: doesnt show up an E46 BMW coupe does it?  Come to think of it, it didnt show up an E36 either...or an E30...
