I have the E1 myself and you're right, it does seem under scale. But a lot of vehicles are like that in this hobby. A lot of guys don't realize that the M41 Walker Bulldog is actually closer to 1/14 than it is to 1/16th. Then there's my 1936 Mercedes 540K. The box said 1/5 scale but I did a little research and they only made 3 different wheel base lengths for that car in 1936 but I couldn't get it to match the model in 1/5 or 1/6 scale. I think it's somewhere in between, but it's close enough for me. The 12 inch action figures fit in it very nicely.
