I like big guns and I cannot lie

No it's not! That garage is far too shabby to provide shelter to such beauty. I demand a renovation.

But how will you majestically burst through the wall when the ATF- I mean RCMP- I mean FBI- I mean invaders is about to breach?
Like in the history books when tanks were hidden in barns and silos!

I concede to your point. I suggest strategically placed moss and cobwebs to enhance the ambience.
