So you are good at making cars look nice. What does this mean? You can do paint and body work? Do you know how to weld? Do you know how to mix paint? Are you good at doing hog ring work on interiors? Do you know wiring and electronics? Do you have a place to work that can have car parts scattered all over for extended periods of time? Are you best at polishing and detailing?
Where you are at skill, tool, time, and money wise will determine what type of project you should look to tackle. There are basket case E bodies out there for a few grand, but they will require extensive body work. Extensive being the need to replace quarter panels, floors, roofs or more. These are skills that are pretty extensive and they don't even get into the drive line or engine mechanics.
Obviously you can learn all these items. But help us know what you can do now so we can provide suggestions on where best to go.
