Go wash your mouth with soap
The wrangler in its default config is about as useful off-road as a 4x4 fiat panda. It'll tackle quite a lot, but it requires speed, being rough on the car and driving it like an american. It's too light to get decent traction in a lot of situations. (Almost any Wrangler you see off-roading has been modified to the point it's barely the same car anymore). Any replacement model for the defender needs to be able to handle off-roading out of the box. Not through aftermarket parts that all together cost as much as the car did to begin with.
