Haven't seen these before:

Sinn 656 MX-5 (Miata) edition:



Sinn Evolution IX (Mitsubishi):




Sinn 757 Polizeihubschrauberstaffel


Pictures obviously from the auctions in question. I'm not posting the links as per policy, but I'm sure you can find them, as it's not like there's a lot of Sinn's on the bay.
