I shortened my post a lot from original so I see where the confusion comes from. I will be moving to Europe for 4 years hence why I have the ability to no kidding purchase a 70 directly from a current owner, all while getting someone else pay to import it to the US when I return home. The one constraint is the part of Germany I will be moving to requires diesel vehicles to either be built after 2016 or be more than 30 years old and registered as a classic. $25k gets you a 30+ year old 70 with 100k miles, or a 10 year old Wrangler with 100k miles.
The rest of my post is in reference to Toyota trying to sell the 70 in the US today. The $20k difference is best estimate for a new US 70 vs a similarly optioned Wrangler.
I had a 2 door Rubicon for 12 years, weld in cage, 35s, well built for rock crawling in Moab, New Mexico and Arizona. Sold it because putting kids in car seats via the soft top rear window gets old quick (more of a problem with 2 doors than an issue with the Wrangler). That and it was going to sit in storage for 4-5 years as we are taking wife's Prius to Germany, and I couldn’t sleep knowing a good rig would be sitting at my parents' house in the AZ sun with all the rubber parts just rotting away. I wheeled the hell out of that Jeep and while I damaged parts off road a few times due to my own stupidity, it never broke down, never failed me, never left me stranded, never had to do a trail repair or be towed (mud doesn’t count). Yes, I did have to repair damaged or weakened parts once I got home, and death wobble was an acceptable part of the experience. This was a 2007, universally considered one of the worst years Jeep ever made. However, I am fully aware of the Wranglers reputation and my personal recommendation to anyone looking to buy one is to by a 4Runner instead; unless they already know exactly what they are getting into, are looking for a street legal rock crawler, and have a serious need for a front locking diff.
On a more philosophical level, Wranglers and 70s are built for a very different duty cycle. Wranglers are built for very easy living 99% of the time and extreme punishment/wheeling/rock crawling/mudding 1% of the time. 70s are built for constant medium to hard going 100% of the time. Parts can and are designed to meet the different needs of the customers with their different duty cycles. I look at the Wrangler as a "glass cannon;" basically the equivalent of a WWII tank hunter: huge gun, hit and run with little to no armor. The 70 is a serious, main battle tank designed to stay in the fight and duke it out. If I was spending a year traveling South America or Africa, there is absolutely no way I would take a Wrangler. However, in reality, I won't be doing any long term travel while the kids are still young, so a 70 is not the right choice for me and the family. I don’t know if a Wrangler will be that right vehicle when I get back to the states, but I have 4+ years to figure that out. I suspect my rock-crawling days are behind me, so maybe something else will fit the needs of a "family camping vehicle" better, but that is a discussion for a different thread.
Also, I would never consider a Grand Cherokee, or anything else from Jeep for that matter, as they are disposable junk. But I wasn’t talking about Jeeps in general vs Toyotas, nor was I talking about 100 or 200 series as they fall in a different category. I have owned 2 jeeps, the 2 door Rubicon and my first car, a 96 XJ. I have owned probably a dozen Toyotas (I have lost count), so I am extremely confident in Toyota's reliability. As a minor counter (and random thought not connected to the Wrangler vs 70 discussion), my parents had a RAV4 burn out a transmission at 105k miles; so even Toyotas can have weak points or flawed parts.
So to actually bring this back to the discussion at hand as to should Toyota bring the 70 to the states, what I have concluded is while the 70 is far better for 95% of the world, it does not meet the wants and needs of most Americans. The end result is I simply don’t think the 70 will sell well enough in the US for Toyota to bring it over. Even if the 70 was sold here, I would recommend the 4Runner for 90% of people as it is a far better DD and good enough off-road for most family camping trips, Wrangler for 9% of the hard core wheelers, and maybe 1% of people the 70 for the long term off-road living.
