Thanks mchale
Spencer, I know how that goes! Building any car isn't cheap, but it never ceases to amaze me how much some KITT replica items are. For example, I was looking on eBay for some interior parts a few years ago and there was a guy selling "KITT Knight Rider doeskin" dashboard trim pieces for a pretty penny. Funny thing is, KITT had a black dash and not tan. As with anything else, knowing what to look for and where to look for it can really help you.
ThunderChild has kindly offered to provide an interior that could be modified for the KITT models. He did a very nice render a while back, here is the link he sent me:
