Horizon/Comet cars

[csteitz]

Hey guys,
Does anybody know of a company that makes these I can't seem to find any? If not which passenger car would be the best to start of with, or would I have to make one completely out of scratch? Here's a link to a picture of one any help would be greatly appreciated.

If its something more modern, you're looking for, try these:http://www.athearn.com/Products/Default.aspx?ProdID=ATH10122
