Oh Marc, now I'm Husky man and would love to own a TC510, but that resto is absolutely horrible no matter which way you look at it. It may have cost a bundle to do and probably is a rocket, but he should have kept it in at least original colors. As someone has already stated it's actually de-valued the bike rather than increase it's value. Maybe I'm being a tad harsh here but the only word that comes to mind is YUK! Each to his own though, whatever "floats your boat".
Cheers,
K
