I take the car to Harrison, and from Harrison (Path train) to either world trade center (last stop)
which takes about 20 minutes, the drive to Harrison also takes 20 minutes.
You can chage on path to get to the port auth.from there you take NYC train.
I work downtown, so i get to work within one hour, I also get home in 45 minutes.
its about 100 to $145 a month to park depending how close you want to be to Train in Harrison.
I lived in BKLYN my whole life, lived on water with view of city and statue of liberty
and it ook me longer to get to work from Bklyn due to traffic.
As far a buses go, I have not look into it yet, but i know it will take more then a hour.
Hope this helps.
