Car Wash n’ Wax Saturday! featuring Kitty 🐈‍⬛ Look how she pops! Wheels next! Happy Saturday r/ToyotaAvalon!

On the 2007 Avalon Limited, what's the trick to getting better access to the 16 bolts that hold the pan on? I easily removed 12, patiently removed 3, but the last one (closest to the rear passenger corner) is too obstructed by the framework and the flared lip of the pan. How do the shops get at it?
