Ha! I found several more Tiger Snakes while romping around looking for Retaliation figures at a different Toys R Us. They were selling for $5 a piece and I bought them all. I'm actually happier that I found these than anything I could have found for wave 1 of the upcoming (And delayed) film.
This is a good find for me as I like the vehicle and am particularly happy to be able to assemble the Street Vipers into a small squad now.
I think I have found a variant that's gone unnoticed.
Out of the seven Tiger Snakes I now have, five of them have a matte finish, but two others have a smoother gloss finish. In the image above, you can see the gloss finish on the rip-launcher of the top-most box. The other four it rests on are matte-coated. It's not easy to tell the difference in the images.
The gloss coat also covers the main body of the vehicle itself, here is the best I could do to display that below:
You can barely tell with my camera and lighting, but the one on the top is the gloss Tiger Snake. I find the gloss significantly nicer looking than the matte finished one below it.
