137 is in the middle of the endzone. I will forewarn you, the endzone sections do get a little belegerent and the fans are loose with their language.
But the view of the playing field is spectacular, love attending Lions games and cheering loud.
Have sat all over Ford Field and there are some great seats even on the 3rd level. Just according to what your seating preference is, but I was very happy with 137. I used to have season tickets there.
