GR8 PL8S, part two

Seen driving around the Bay Area yesterday:

UPTNOGD  (on an old, rusted beater Subaru)
THX BAIL  (does a bail bondsman own the car?)
GUD FOOD  (just the kind of food I don't want to eat)
DUBL 8  (the year I graduated from high school-- them too?)
TT TUDE  (on a super-cute Audi TT convertible)
