If there is a review of a 360 Modena, it will be from circa 1999. Not a good time for Top Gear as Big JC left the show in about 1997. At the time TG's resident testers were Tiff Needell and Vicky Butler Henderson.
I remember seeing Vicky BH testing a 360 CS, but I think that was from the 5th Gear show in about 2002/3 not TG.
Might also be worth looking for episodes of 'Driven', that was the show that was hosted by Alain De Cadinet, I'm certain it was shown in the late 90's. If anyone was going to test a 360, I'd imagine he would have done.
