My '01's engine has a greyer tint to it than my friend's '02, so the colors may have changed. There's a Testor's model spray paint you can pick up at Wal-Mart or your favorite hobby store that's a perfect match for the '01 and older, but it may be a little off if your '02 is the same color as my friend's.
Look in the FAQ's for the Testor's color # or the search feature if you don't readily find it.
