Strong money for a 2004 MX5, as for the rust they all do that sir the NB being the worst offender of the range.
Apparently this is a Camera car used on the Grand Tour etc. the D3/4 is used a lot for mobile Camera work as the upper tailgate can be lifted and the lower one left up for a little safety. The upper tailgate glass has been replaced with lighter plastic to help it stay up on the move, and the exhausts are routed that way to help keep exhaust fumes out of the cabin. I'm a D4 owner, I've had several D3s and 4s, and the DISCO4 Forum is a good source of info like this site.
