It's all relative - your $ numbers are limited by your financial limitations / situation, just as a 20 yo would look at your $60-70k jeep and laugh and try to convince you a base Ranger 4x4 is the right answer since it can do 95% of what your jeep can do for $35k with a backpack, some rubbermaid containers and the stock bumper with a cheap winch. There is always something cheaper, faster, better, etc. You came up with what worked for you....it's not the right answer for everybody.
Check your numbers again, you can build a nicely equipped Defender for well nder $70k. I bet it's $5-10k, at most, more than a comparable Jeep....I built one how I'd build it with the 4-cyl...which compares favorably to the Jeeps 6 and the adventure pack, offroad pack, cold weather pack, towing pack, heated seats, wheel arch protection, 18" steel wheels and even threw in a snorkel....MSRP is $59k, but does include some thing the Jeep doesn't have, so not 100% comparable.
