If you're looking at resale of course you'd need to go factory plated colour to maximise appeal and resale price. But if the cars for you to keep I reckon go with a model correct colour that you're going to love. You are the one who will spend the most time admiring it.

And its not wrecking it, how many sandman on here are on their 2nd, 3rd, 4th? incarnation? Whilst your custodian do what you like. Car can always be restored again in 10-20 years time again.
