NFZ W43 2

This is simply amazing!  Looking at it more closely, I start thinking it looks somewhat like a car transporter of sorts.  You could keep the rear fenders as they are but flatten the "bed" to accommodate on of your other vehicles - something like the W42, perhaps.  I don't know the scales used and maybe you'd have to lengthen & widen the wheelbase but I think that would be something cool to see.  Is it possible to combine two vehicles with the Apps you're using?

Regardless, this is a real beauty; congrats!
