Fun fact: There was once a Lego Audi TT set.

And it looked like this:

It was a promotional set released in 2002 and sold at Legoland Deutschland, and it is extremely rare. There appear to have even been a couple minor variations of it with different wheels as well, some of which are a bit weird:

I can tell you from experience that that wheel and tire combination will not roll well, those tires are too large for that type of rim and will rub on the axles. Perhaps that’s why they made another version of the set...

But other than the nifty chrome “macaroni” bricks that make up the rollbar, these are all fairly common parts and it’s not a complicated design, so you could easily build one yourself if you wanted.

So there you go, a bit of rare Lego car trivia that no one talks about!
