original color or change
I'll add my $0.02 CDN and say "Keep it Original".
Pull it out and wash it good...then look at it REAL close...for a long time. Think of all the work you'll have to do to change colors....interior, dash frame, carpet (looks like you've already made a decision there), inside trunk and engine compartment (pull the engine, clear the firewall, etc.) , upholstery, and on and on.
Like what has been said...it's only original once, and, for retaining value, original is better.
