Getting VIF from R

Hello!
I was wondering how to get the VIF value for predictors in R (namely, in the context of Logistic Regression).

I have read that there is a command for this in the 'car' package, but I am unsure as to what of the two returned columns of VIF must be taken into account.

Related question: is there a reference as to what VIF value should be considered a threshold above which collinearity can be considered an issue?

Cheers
