[Ascaris]

Original is certainly less hassle in some ways (lots of painted surface in inaccessible areas). However, you still have the hassle and cost of getting a custom match to the original color.

And for that matter, deciding which section of the car will become the "match" for the original since the old paints fade differently in different areas. I took mine from inside the trunk.

And if you want to retain that '70's feel, nothing like Mayan Green.
