These Cars are tough
 

I was driving my dark horse car (same as an audley) upstairs in my house and it wasnt getting much traction so I couldent control it much

suddenly it went full speed over the railing down falling ten 10 feet straight down into my Tiled front entrace

I thought it was broke and went down

it was fine you would have thought it had been placed on the ground it worked perfectly
I even controlled it from upsairs just after it had fallen

thats a scale 320ft fall with now body damage at all

just thought Id share this
