Here’s another by philip. This one has been more extensively modified than the 510 Rally.
He painted the wheels to look like Fuchs and, more obviously, he cut the roof off. He claims “this is [his] first real foray into cutting pieces off HW cars...after getting a rotary tool” and I’d say he did pretty well!
Sorry for the potato pic.
He also did some interior detail, which is done really well.
He also did a little underside detail.
