I looked long and hard at a GX before I settled on the 100, and the main reason I picked up the 100 was because I found one with the locker and really low miles (105k on a 98) for a good price. I dig the way the GX drives and looks, and they all have the 5 speed which is great. I wasn't crazy about the rear suspension/AHC though that's relatively easy to remove, and I definitely don't care for the tailgate design at all. I much prefer the split tailgate like in the 100 where you can fold it down for a table or sit on it or whatever.
