Right then, I can't see 705 anywhere, but found the others I was thinking of...
701 16v Red, Autocar 16-Aug-95
704 16v Yellow, Autocar 05-Jul-95, Auto Express 21-Jul-95, What Car Aug-95
705 16v Black **FOR SALE**706 16v Green, AutoItalia No.8 May/Jun-96
707 16v Yellow, Autocar 27-Sep-95
708 16v Red, Top Gear Aug-95
709 16vt Yellow AutoItalia No.5 Nov/Dec-95 I drove this at Brooklands and my old White Dino 2400 Coupe was pictured in the same article

713 16vt Yellow, Auto Express 23-Jun-95, Autocar 05-Jul-95, Autocar 1995 yearbook, Top Gear Aug-95
715 16vt Green, Performance Car Dec-95 and Jan-96 Performance Car of the Year (plus VHS video)
718 16vt Red, Car Aug-95, Autocar 1995 yearbook
720 16vt Red, Performance Car Aug-95, Complete Car Aug-95, Autocar 13-Dec-95
So it looks like 701-708 were 16v, 709-720 were 16vt
Fiat used M*** CLM for lots of other new Fiats and Alfa's at time, some may have been on the press fleet, others perhaps company cars for Fiat Auto UK employees, but all of them will have had Fiat Auto UK as the first registered keeper.
