Lamborghini Gallardo - Problem with Hedge Mesh

Ok! I am uploading the blend file as well as the image of the side panel hedge, which has the problem. The artifact on the corner of the side panel hedge as show in the snapshot.

Please help

Get rid of those long thin triangles (never good with subsurf) around that area and see if that helps.
