I bought my Liberty in Feb '07 with 54 miles on her.
She's now at 162K miles, and I've only had to replace a rear control arm and the right rear passenger side window motor up until recently.
The left rear window just crapped out a couple of months ago, and I'm about to replace my water pump and fix a leak in the evap system, but after 6.5 yrs, I can't complain.
She's been the most reliable vehicle I ever owned.
Took a hit from a light rail train that clipped my driver's side sideview mirror.
It didn't even take the arm off, only the mirror itself popped out!
A freaking train!
I was in an accident in Dec and begged my insurance not to total her.
So yeah, I love my Liberty.
I love that the window controls are between the seats, and not on the doors.
No worrying about the dogs stepping on the button and choking themselves.
Plenty of room for 5 people.
All around fun vehicle to drive!
Better motors for the windows, since that seems to be a major issue with a lot of Liberty owners.
