Everyone has posted some great points and opinions. Numbers matching does effect the price if you have a car that is mostly original and if you intend to restore it to original condition and get it judged for originality. Cars that have been judged at Bloomington Gold and awarded a ranking always attain a higher dollar value. All that said, it depends on what you do do with your car. Do you want to to be all original, a reso-mod, or all out super custom show car. It's your choice and your money.
