I nearly bought a set about 12 months ago for my black Polo. In the end I didn't bother because they were LHD fitment and not RHD like I wanted. Plus after asking the advice of fellow Polo owners almost everyone agreed the car looks best with the standard red clusters!
So for now I've still got the red ones, but a few members on here have got those clusters in the picture, but in smoked grey, and seem to like them quite a lot. I myself might get a set next year, I'm still undecided. But if you like them, go for it!
Cheers
