Correct, it's Renault!! I've forgotten...
This model of Escort is becoming rare to see here (I've seen about 4 in the last years), one in a really good shape and the others all fcked'up...
The only models of the late 60's and 70's that can be seen around here (in "usable" shape) are Chevrolet (Chevette and Opala) and VW (of course...).

About the cage, yes, it's bolted. I want this car to be a street legal, but here in Brazil the traffic law is passing trough some changes, so it's not fully defined if it's legal or not to use the cage...
