Personally I'd go for a Phase 2 over a Phase 1 or 3 - I don't like the nose on the phase 3 and the interior is in my view better than the phase 1 (the Momo leather option is better than the leather option in the phase 1).
I'm not sure what the price difference is between a Cup and a standard GTV - I know the Cup is a limited edition but it used to be much more expensive and to be honest I've never fathomed why. I'd prefer the full leather seats in the normal GTV than the half leather seats that were in the Cup - althugh apparently the Cup's are more supportive.
Its a case of you pays your money and you takes your choice!
In every step, I hear your sobbing
Dare I break the shade with one caress
Dare I trespass to lift the veil
To touch the lips so soft and frail
It may be that love comes once and once only, preceded by rehersal, followed by regret.
Know well that however right a man may be they always find the fallen one guilty.
All that is required for the triumph of evil is that good men do nothing
