I got spotted twice in mine.... both by cliosport members - once on the m4 on my way home from work, and once in Alfreton Derbys some 150+ miles away - and I was only up there for 2 hours!!!
Mind you, other than at meets, I've still only ever seen 13 vee's on the road... (5x mk1, 7x mk2, and 1 x-reg pre-production), that's over 7 years of looking, and I do about 40k miles a year as well, so I'm more likely than most to spot them!
In my anorak moments I keep a list of each one I've seen on a pad in the glovebox so I can record every sighting!
