Putting Leather on my bezels!

I hate the plastic interior in my mustang. It is soo uncomfortable and looks SOOO cheapp! I was thinking about putting synthetic leather trim on my doors, dash, center consol, and my custom 10" touch screen bezel. I was wondering what you guys think about it.
I want to use synthetic leather b/c it feels nice and it's as bad in warm weather like real leather is. I am also thinking about putting so kind of cushion between the plastic and the leather to make it more comfortable, like memory foam or suggestions on that would be very nice too.
I have seen it done in a corvette and I know i said I was thinking about selling my cobra for a corvette but i'm keeping the cobra and just buying the corvette. I was also thinking about replacing my racing seats and putting in some leather seats and any suggestions on that would help too.

Do you know of any places to go to look for the foam? I'm thinking of doing black leather with white double stiching.

Yeah..
I did google some stuff. I can't really find anything at all about it which sucks =[. but kool because that means it isn't a very common thing people do to their car. I did see one site that makes custom full leather interior for corvettes but that was about it and that is the same excat thing I want to do but I want to put padding between it and the plastic.
Any ideas about materials wut help soo much.
