Hopefully for the Estoril owners the following won't happen...
There is a risk that (judging by the forum) the majority of S3's sold are going to be in this exclusive colour, which is exactly what happened to me when i bought the MK4 Golf R32 in that exclusive blue (can't remember the name) and when i came to trade it in the dealer was like "everyone bought this colour so they haven't held their resale value blah blah blah..."
And they are the target of alot of jokes on the VAG forums...
I do still maintain however that one should choose a colour by personal preference, and not what others think...
