Well, the open air in Northern Europe aren't fun in a Wrangler. It can't tow and can't carry anything, the quality is abysmal, and it is generally a toy.
Hell, why not get a Mahindra, mpinco?
If I wanted "the best" vehicle for obstacle courses (not "offroad" as you keep conflating the two) I'd get a trials bike, or a road legal MX bike. Much better off road than the Wrangler. Oh, so you don't want "the best"? You want four wheels? You want seats, a steering wheel, and so on? You want those solid axles so you can modify the vehicle and inflate your "image" in the right circles? Yeah, those options aren't the best.
And once again: Your obstacle course is an extremely small part of what "offroad" means. Hell, I'd so purchase an amateur (i.e. cheap, not very powerful, not very comfortable) rally car over a modified rock crawling Wrangler.
The next collector vehicle will be the 2nd generation Jeep Cherokee XJ. The younger crowd loves them.
The Land Rover Discovery I has that potential down the road. I don't see any of the new LR's achieving that desirability.
Maybe in the US and around your parts in particular where it seems "cheap" trumps everything else. The new Defender is a global vehicle.
