You want my bet? WK2s will outlast ZJs. If a ZJ makes it to 25, a WK2 kept in the same condition will make it 35. Technology, man. It improves reliability as time goes on.
Besides, saying something has to be ancient to be good is ridiculous. It doesn't need beam axles or pig iron to do stuff. I suggest you watch what a WK2 can do.
I shouldn't say the WK2's are junk, and I'm sure they perform well. But to say all this new electronics and technology improves reliability, I don't thinkso.
This I my friends 91 cummins 12v. It sat underwater for 3 days in a severe flood we had a few years ago. We dried it out for a week. Been running since without a problem. Has 280,000 miles on it. Do that to a brand new cummins and see what happens.
You're making false equivalences. WK2s haven't been around long enough to have 200k miles or be submerged in as many floods as ZJs. Nobody knows what WK2s will be like down the road, but the same thing was said of ZJs when they first came out, with their power heated seats, automatic air conditioning, rain-sensing wipers, 10-speaker audio, electronic automatic transmissions, and multi-port fuel injection. But ZJs ended up just fine. I have 250k on mine. And that's with Chrysler's legendary bad electronics in the 1990s. I'm optimistic about the WK2. I think it'll go the distance.
