Thanks guys, they work out to be around 90,000 poys each, I made them in Modo. Each model has one 8192px x 8192 texture map, with bump, specular, etc.
I've been working on them on and off for about half a year, I'd say about 60 hours work total. Once I get a few more liveries tucked away under my belt I'll probably release them, if anybody's interested.
Cheers
