does anyone know where i can buy a mesh grill for my 1999 omega B 2.5 V6 Saloon
In short, you can't.

(Waits for the first pic showing that you can

)
I gave up looking and used Reiger Mesh and designed it myself. I did this because I wanted the Mesh to be flush with the front edge of the Grille. Most of the stuff I'd seen on Omegas (Pre-facelift that is) sits at the back of the grill which was a look I didn't want.
There are Mesh
looking ones on Ebay, but they are usually made of thicker more rigid metal.
Ths is for both Pre and Facelift as far as I can tell.
The Vaux/Irmscher type were nearly all of the horizontal black plastic slat variety.
As has been asked already, is your grille on the bonnet or does it sit between the headlights in front of the radiator?
