I am enjoying the new S3 configurator (US) / configurer (UK):
matt colour might be a good alternative to the pricey decorative logos etc
kite decal breaks up the side blades
not sure how well the side carriers will work with typical road muck / light fingered brigade when parked - probably the rear luggage rack is still more practical for long distance touring vs picnics
full windscreen looks bland compared to the M3W's (Morgan or Fairbourne) and misses the central strut to put on a rear view mirror
footwell heater is probably a good idea vs the heated seats (which will probably vary with your view on the latter - I have them and dont use them)
