I'm always one the fence about painting vs. original. I tend to leave original more often than not but a lot depends on the bike. It the bike is a common low end bike that's not complete or if the bike has been clearly overly abused/vandalized/neglected I will repaint and fit it with quality chrome and parts making a truly custom one off. On the other hand if the bike is unique, rare or only suffering from patina due to age and use I do everything I can to keep the original paint. I love the patina and age but there is a big difference between neglect/abuse/vandalism and age/use

All in all I don't get upset with a repaint unless it is poorly done in which case you're just abusing it. I have a 50s ladies ccm that has been previously brush painted.... clearly I'll repaint it.
