I agree on the van NOT getting the open window option returned,
they did not give us the open hood it use to have!!!
I had both the 1971-issue Rescue Van and the "New for 73" Surf Van back when - and still have the bodies. Neither of them had an opening hood. I was disappointed in that, and cut both hoods out to hinge so that at least the front of the engine could be seen.
IIRC, none of the AMT Chevy Vans had an opening hood. The FORD vans had - and still have ("Phantom" (ex-Vantom) an opening hood.
If Round2 DOES indeed bring back the multi-panel body and stock parts, it will be serious kudos due them.
