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...
