Mercedes leather is the most common here in the US for car upholstery.
Johnny is absolutely right, leave the dash 'til last. It's a little tricky. The console isn't easy either. Looks simple but it isn't. You might want to consider making a console cover now. Mounting it. The do the upholstery on the entire thing.
Johnny. Maybe there is a market for you to do patterns for the car? I remember when I bought my first cargo van. There were pattern kits that were available to expedite paneling the interior. You had to figure out where to put the black light, and lava lamps yourself though?
