Unless its a used car dealer they will probably ship the car straight to auction anyway, or they have someone buying stock regularly from them, so i wouldnt worry so much.
Even a used car dealer wont care about such a cheap car - especially when part exd against an expensive one.
When I part exd my Rover for the Punto they never even looked at it (that was a 2nd hand dealer). We removed the tax disk, stereo and my mate even had the floor mats out! Dont worry about it.
