any car you get regardless of color will be hard to match unless the car is brand new and all of a sudden you need say a new door and you get it from the factory, even then you run the risk of a color shading problem. just what was said in the first post, get two doors that are silve and wehn you get the cash, paint the whole thing. Do you know what kinda paint you want to use? and if you choose to keep it silver, it will be easier to go over it withouth the tons of sanding if it was a red or something. not sure if you can do this where you live or if you are capable of doing it (not knocking you, some people just dont know), but you may be able to cut your cost if the paint shop will allow you to all the prep work then bring them the car. Most your cost is the labor for prep. work.
