you realy should get your facts straight before you start trashing a car you obviously know knowing about.
Yes jeep can have death wobble but only when you are dealing with worn out suspension or steering. Which if the jeep was propperly maintained will not be a issue.
secondly the trans in the jeep are as good as the engines with proper maintainence will easily last 200 to 300k they don't need to be flush or have any of the band packs adjusted. just fresh fluid and filter every 36k miles (maybe 45k can remember off the top of my head.)
Only issue I would look at for the jeep he posted is the head if it has that 0331 casting it could crack.
\and your sig is too big.
