- Who said we didn't expect breakage? You should see the video slo-motion
- footage we got out of this ;-)
-
- anyway, he was barely 6 inches off the ground since he couldn't get any
- traction in the snow. A vehicle that is sold with slogans like "only in

- (ab)use for the last 130000 miles without a hick-up - well, that's at
- least what my friend thought.

- Strange - my Toyota has a mix of metal and rubber mounts with some quite
- hefty bolts in there. It took the jump like one of those nasty potholes
- you frequently hit with your stock vehicles downtown...

- Hey, good question - we stopped our jeep-riding menace friend from
- trying out the fresh ice on a lake nearby. He was sure his Jeep
- wouldn't break thru, while the ice was cracking under his feet across the
- entire lake just from his own weight. Jeep - there is no substitute...
