This isn't the clearest photo; it's all I could manage with the camera on my phone. What you're looking at is a VERY dirty car, one that clearly hasn't been driven in AGES, simply left parked on the side of the road.
Someone must have walked by it enough to think it might be abandoned... Or at least no longer wanted by it's owner. What to do? Well, simply write "I'll buy it" on the window, by tracing through all the dust and grime, also leaving your mobile number.
"I'm not selling" was the reply later left beneath.
I'm not sure why, but I found this very funny.
