Wow, this post took a turn I wasn't really expecting. Yes I do know the actual cost. But you know what? That number is irrelevant - there are so many things that dictate what it ends up being. First, and foremost, it depends on your starting point. Is your project a pile of parts? Is it a pristine barn-find? Also, as with this project, there were some unforeseen 'gotchas' that added to the cost. Additionally, in my case, I got to a certain point where I had the disposable income, said 'screw it', and just made a slew of purchases of new and/or NOS parts to complete the build. Anyone else's experience WILL vary greatly.
In my mind, I was trying to stay under what I felt the value of the completed bike would be. But again, what exactly is that value? In truth, the bike is only worth what someone else is willing to pay for it. I have a personal standard when I'm doing restorations, so that drives most of my decisions and the final outcome. Is this bike a '100' on the AMCA scale? No, but it pleases me and generates the expected positive responses from most people who have viewed it.
To quote an oft repeated statement: If you're doing this with an eye on making a profit, quit now. Otherwise, do what pleases you and you will be happy with the final outcome. For me, this isn't a hobby, it's a passion...
