wcc,
Have you been to Sportcraft in Laingsburg? They have a ton of slot cars, big and small. PLUS, the owner is a Porsche guy. Mark has an early 70's 911 he has had since new. He has it in the back of the store. If he is there, ask him to see it. It is original with a cool patina.
www.sportcraftcars.com is his website.
