My Dad had 2 different ones. a 100/6 and a 3000.
The 100/6 was a light blue over white like your AUTOart (I have the Ertl) but was eventually painted red.
The 3000 was a very odd and un-original brown. :cry
I have had a picture in a book on AH with the Dark Blue over white 3000 that I have lusted for for years.
So in about a week I should have my dream car in 1:18 :lol
