That’s a JK. This is a TJ forum. The thing is that everyone here would want to see frame pics, and that dealer doesn’t show any frame pics. If it’s been in Dallas all it’s life, the frame would be fine. If it migrated from the NE, the frame might have rust.
The thing about the 2007-2011 is the 3.8 engine was severely underpowered. It also leaked a lot of oil. I’m sure others could add some details, but the JK forum may be a better fit.
