Since you are in California , there is a pretty active Vintage Bike Scene in the Sacramento, Los Angeles and San Diego areas . Pretty sure there is a Colnago just like what you want sitting in someone's garage waiting to sold . If youre not in a hurry, buy an old bike ( they are really cheap right now $ )and join in on some rides,, a few of my current bicycles were bought from friends Ive met at those local rides . I have a friend with 3 Colnagos sitting in his garage that he's trying to sell ,, they are not your size though . Good Luck on your Colnago Quest .
