The Arrowhead Panther IV is the most popular of all the 'Marpor' muscle cars, so much so it became one of the planets first export successes, though the ultra polluting engine used to help terraform Mars had to be replaced with more standard engines for off Mars use. Most were sold in the team racing colours of the Octan Fuel Company, but of course without the Trademark logos which would have required a license.
I love this thing, yeah it's basic, and huge for one mini-fig, but the lines are great. I might try building a few in different colours if I do more of these Mars highway MOCs. It was fun, so it'll probably happen one day.
Wow! Very detailed and sleek. I'm not much for cars, but this one would top my list! Oh, I didn't really notice, but now I did, I like the note on how the emissions were used to terraform Mars! Nice! I've been reading on that lately and so I thought that was a nice touch.
