How do I remove cars from background?

This was just a snap, but there was no way to take a neutral background.

I'm mostly a LR 4 user and have Elements 11. Reducing this background clutter is beyond my skills.

Is there a way, in Elements, to clone the wall and street over the messy looking cars and trucks?

I know how to add a completely different background but I'd prefer it to look natural. And I still won't know how to fix the cars seen through the windows.
