Depends on the type of person you are going to be selling it to and if you are painting EVERYTHING. Original color really only matters in the Oldsmobile Club of America and other national type club shows. It'd be in a modified class instead of restored class.
I'm too lazy to look it up...is Meadow Green light or dark? Personally (and most people I know) don't like that Oldsmobile light green.
Myself, I'll be doing show & shines and maybe run to some regional OCA events. I'm repainting it to please ME. I'm going with a late 80's Corvette red (Code 81) and white hood stripes. Nothing sexier than a red convertible!
Of course, that's assuming you aren't painting it some weird lowrider job with 27 shades of metalflake purple, yellow and green...but I judge no man.
