That's totally cool! But again know your audience LOL I have alligator skin seats Beaver skinhead liner and an ostrich skin rear deck LOL..
Word of caution about the dash... the recommend taking a big chunk of whatever you feel you're going to put on the dash and just laying it up there on the dash and pulling the car out into the sun... When I was a kid and I lived in Florida I thought it would be really cool to cover my dash in my 82 trans am with some black and white camo material I found... Man I thought it looked cool as heck! I pulled out onto the road in the sun and could not see a thing out of the windshield lol... That day I learned why they put flat colors on dashboards...
