None of the bikes on your list are Italian. A poor start.
1. Provenance: Has to be Italian, or at least have Italian kit on it. If you can't manage that then get one you've seen an Italian pro ride.
2. Paintwork: Must, ideally, be foul or irredeemably naff. Good examples are Colnago (frequently both foul and naff, horrible colours and the occasional F-14 fighter a la top gun), Pegoretti (Elvis and upchuck paintschemes) and Bianchi (in inexplicable shade a of colour not normally found in nature). If you do go Trans-Alpine and into the world at large it helps to have a bike that looks like it was designed by a colourblind Milaneese 4 year old in the dark, as this may fool people for long enough to let you get away with it. If you are French, Look and Time are acceptable.
3. Team Kit: Now, this is important. You can't go around in a pink Bianchi jersey on a Pinarello, you'll look like a right dog's breakfast. Consider what you are going to wear with the bike, this will help you narrow the field down from the start. If you do insist on wearing the jersey of a major team, make it one from several seasons ago, this gives you an air of seniority.
