I do like the st170 in blue like yours, I might even swap my black car for one later in the year.
If you really want a supercharger then you might have to dig a bit deeper and get the kit from TTS Performance which should fit on a ST without too much trouble. I thought the price was a bit steep but looking at the price of used units from a VW golf which are similar its not so bad after all and that's the problem a turbo install would be half the price.
