Saying 'I do not consent' may not keep your car (or person, or home) from being searched, but saying 'I consent' will guarantee you won't be getting the evidence suppressed.
Saying yes to being searched when holding will produce a guaranteed result, barring dumb luck. Saying no may not prevent you from being searched and even convicted subsequently, but it brings the possibility of not being convicted, and you might even run into an honest cop who will let you go on your way. Believe it or don't, most cops are honest people.
