I'm not that fussed about how they look tbh, I was always more interested in how the mechanical repairs were achieved because there was a chance I'd pick up the odd tip.
With the custom build shows, many of the mechanical bits come out of a box brand new and all they need to do is find a way of getting it to fit.
Remember Orange County Choppers?
I spoke to someone who ordered some quite expensive parts from them and it was all show chrome* that wouldn't have lasted a year.
*You'll have seen it somewhere, it's the type of chrome that blisters and flakes off.
