Julio/blasco-
as suggested by others, it's all about lots of research so you know what you are getting into.
I got a very very clean car with neusence only issues by the time my VS was delivered to Seattle. But I did visit VS in LA several times during the build/after completion/before shipment to shake it out using the list provided by Gordon... Glad I did... Car was completed first week of July, but not shipped till Sept. Kirk was Awesome.
the stock 1915cc continues to run strong- ~15,000 miles later... I drive daily when the sun is out, and from Seattle have driven the speedy to Lake Tahoe, central Oregon , and Revelstoke BC - Canada with nothing but a flat tire and a clutch cable replacement. ( well ... And some carb tuning to adjust for altitude changes)
I'm only considering a new CB because I'm craving more power.... There are other great builders out there, but Pat has been awesome educating me/answering questions and he's the guy I will go to when I'm ready for my new dream engine.
im happy to answer any Qs... But as said by others it's all about education and understanding that your buying into a lifestyle that includes a AAA Pluss membership with up to 4 annual free tows a year, and making friends with other vintage car lovers who are willing to teach you how to work on your car/ or work on it for you to keep it road worthy.
its like owning a classic, but better because you can drive it anywhere ;-)
