I had a VW Porsche 914 (typ 4 engine 2ltr) until my spine refused to use it anymore seven years later (also it wasn't in good shape when I got it, and wasn't getting better over time), in that time I made some friends in the aircooled VW scene.
And since we never had enough money at hand, we always repaired them ourselves,
so I spend a lot of time on my back under different bugs, bullis (T1&T2), an 181 and a Typ3 and of course my deathtrap,
unfortunately no Samba (one reason why I want one I guess)
I was hoping you add windows (23

) to make one to be honest.
With Safari windshields

But any T1 is great to have!!!
And the T2 is also a very cool microbus, I like the tintop more, I never was really into more head space, or even those folding tent roofs whatever you call them over there
If I had to choose, a beige white safari windowed Samba with polished 15" Fuchs wheels (911 from the 70s)
I think for the kids I'd go for a more colourful paintjob than darkgrey and white lettering,
don't get me wrong; very cool looking that way, but for kids *shrugs*
Anyway, I'm already impressed and I'm sure you will end up with a Kart I'd love to be able to build myself
