I did the same thing: knew the redesign was comming, and figured the TJL would only be in production for a year or two before being scrapped altogether. And I knew that the I-6's were about to become another footnote in history, which is sad: straight-6's in trucks aren't being produced anymore, and IMO, they're the most durable engines ever produced, topped only by Dodge's famous 225 ci. slant-6.
I hate to say it, but I'm in Kate's corner: yeah, the KJ's look like smiley-faced mall rats, but underneath, they're just as rugged as TJ's; I just liked the front/rear live axles and that straight-6 too doggone much to pass it up.
Hmmm. Keep talking about it, and I might have to go sit in one again. They had a LOT more room than a TJ, rode better, get better fuel mileage, and scooted quicker. Cheaper too. Hell, I might have to go sit in both '07's when they come out later this year to see what I'm missing.
Incidentally, I didn't end up haading for Tahoe after all. Had some minor 'guy surgery' that has postponed things for a couple of weeks. This sucks. Hate sitting around the house all week with nothing else to do but read newsgroups. Bleh.
One must wonder if the Unlimited's will have a higher resale value due to the short production run and being one of the last I-6 powered TJ's. Hmmm.
