The "ideal" garage/stable I have in mind would consist of these:
Racing - Maserati Grantourismo S: White / Full carbon Italian beast. Campagnolo all over the place. Bling bling bling.
Winter Trainer - Mazda Miata NC: White / Aluminium Japanese excellence. Shimano 105 or Ultegra. Fast & reliable.
Vintage - '67 Alfa Romeo Duetto: Blue / Classic Italian beauty. 70's Colnago frame with Campagnolo Nuovo Record.
Fixie/SS/Track - Nissan Skyline GT: Red / Street cred / Track day. Two sets of handlebars, one for street with brakes, one brakeless for track.
TT - Bugatti Veyron: Red / All about speed. Full carbon. 80mm rim in front, disc in the back. Not sure about the groupset.
City cruiser / Luxury - Rolls Royce Phantom: Green / Modern elegance. Full carbon. Everything silver, honey Brooks saddle and bar tape. What this thread is all about.
And this is thinking that I would never have an interest in MTB or CX. Which is highly unlikely.
