Folks use your brains, just slow down last nights episode and watch...
...Something totally made up! The whole Robbie struggling "Story"
I know the building they are in, and it's true the car was in the second story, however, that second story is very large and guess what it has in the back? A big bay door with a ramp, that you get to see as Robbie is spinning the car around, it wide open and you can see how large it is! They could have easily taken the car there and out through it.
That elevator is a fully functioning one that's rated for a tow moter to go up and down in. Not some rickitty thing they've never used..lol.
They just wanted to do all that for a filler story.
