I never have.
How on earth do you spot them?
You will see the split tail pipes as they shoot past you

But the badge always says GTD
A bit like all the mk5 ones I see from the front that i think oh look a mk5 GTI then it gets abit closer and its actually a GTsport.
I spotted a few mk6 GTIs when i had the mk5. There easy to spot. Two thick red grill lines, GTI badge. From the rear the split twin tailpipes. The GTD has same front and rear bumpers, fog light design, rear lights, darkened rear windows, but a crome grill and mk5 GTI style tail pipes.
But im sure you know all this and are trying to be funny
