only the early ph1s had them mainly the w reg plates and some x regs although there are a few y plates that had them too. Was just a bit of a hit and miss at the factory if Renault had the lightweight bonnet in stock to fit or not
I`m from holland where we don`t have w reg/x reg/y reg plates
Mine is from october 2000, maybe that helps. I know the first cars where all silver and had alloy bonnets. Maybe when more colors became available Renault decided not to do them anymore?
This is going to sound stupid, but can you tell if its alloy or not without taking it off?
