I wasnt sure where to ask this question but, does anyone know of a good website to order automotive vinyl?

what are you looking for? autox numbers or some w1ck3d k001 gr4ph1c5 4 j00r wh1p?

I like www.harrisdecals.com

Easy to use site with lots of options, and samples. Seems to be reasonably priced. They did nice work on the numbers on my car.

....

maybe im using the wrong term? I mean automotive upholstery vinyl fabric, like used to cover your seats or recover interior panels?

Oh, you mean for a car with an actual interior. I don't know anything about that, sorry.
