Hehe...outside of packaging it in a cadillac?? You do bring up a good point -- I've often thought that for 40k and full independent suspension...it doesn't ride that much better than my Jeep GC did with solid axles. In fact, I think that almost every day over certain sections of road around here!
I've played with tire pressure a bit. It does ride softer with lower pressure but I decided I liked the tighter handling and better MPG by raising it back up. I'm running about 5 lbs psi above the factory recs.
