Standard plate in the middle would look best imo. Again, glad you removed the bonnet bra, not a fan of these at all tbh. I'd be tempted to paint the heater controls/vents black to match the dash surround and CD fascia.
Love the colour but not a fan of the wheels, sorry. Think the GP should have 17 inch wheels as a minimum but then again, spokes that dont go to the edge of the rim also make them look smaller than what they are too.
