I think you actually have more than the land rover shop i used to work for. I thought they had a lot but I believe you've got them beat, not by much though lol.
The z coming along great, wish I had more progress made on mine lol. Quick question though, what kind of wheels are those? They look similar to the western turbines but I don't think that's what they are.
If its the silver one in your sig pic, it'll probably just buff out. But seriously, I agree with rtubo 930, starting with a clean shell would probably be cheaper and end with better results.
Here you go:

And I just now noticed he doesn't specifically say what they are. Hope it helps though.
