I'm not convinced at all by those ID ads.
Why would anyone end up without an ID anyway? Stolen vehicles, sure, but anyone doing a build will start with somthing, as that would be the cheapest way to get a load of body parts.
So I'm unsure if there's demand for all these IDs, and I can't think for anything like the £1.5k etc that they get advertised for.
I'm not saying youre wrong, as I don't know - but I do know there's a world of difference between somthing being advertised for 1.5k and someone buying it for £1.5k.
