I like it exactly like it is and really wouldn't make any changes at all. I don't ride long distances really. 2-3 hours max. My girlfriend does ride with me on occasion but just on short half hour rides. Even so, I'll have to figure something out to make riding on a pillon half way comfortable.
As far as costs go, I couldn't find a new bobber that was anywhere close to what this costs ($10,000). Seems like everyone that makes them charges an arm and a leg. I don't think I could build this bike for much cheaper than it is tell you the truth.
I used to have an 2006 America before someone pulled out in front of me.
