Arne,
It took me all night to find this topic again. I should have liked it the first time I found it. Very interesting and you did a great job on the cars you showed, but I like the Heinz car the most.
Can you elaborate on how you went from photo #1 to #2 & #3...in other words, what did you use to cut the walls from the sheet steel and then fold/form the walls, roof, etc?
Tom
