I'm good with stuff like this anyway, always getting low prices... But yeah, the cars are crazy how cheap I get them sometimes.
I still can't believe how cheap I got the Mercedes, they could have sold it for double. I've had it practically 2 years and nothing big has gone wrong (just age related stuff like mounts), it's a golden goose creampuff. Runs and drives like it's brand new. He just didn't know what he had. I didn't tell him what he had, but I called every single day while it was waiting on a part for the top and not available yet. Said top has worked flawlessly knock on wood for almost 2 years, and we use it a lot.
The LS430, yeah. Got that 17 grand worth.
The LX I got for $500 over what my friend paid, used my broker buddy for that one. Impossibly cheap we got that for.

You didn’t know, but the VVT stuff was not on the original 2UZ. Mine doesn’t have it. Too much stuff on the 4.6 to go wrong and it sucked that Toyota never did any updates to the 4.6. Not one on the GX460 in 13 or 14 years 
my mechanic recently removed one of my cats.
Down to two now.

and expanded the service intervals to 10K. Overall there is more to go wrong which is the big issue. Sometimes the hydraulic chain tensioner fails, loosening the timing chain tension. In the early years of production, the engine was equipped with too thin unreliable valve springs2UZ at least got some updates (I don’t agree with them) unlike the 1UR which Toyota left for 18 years untouched

The 1UR suffers from oil consumption problems. Maybe because Toyota uses 0W20 and expanded the service intervals to 10K. Overall there is more to go wrong which is the big issue. Sometimes the hydraulic chain tensioner fails, loosening the timing chain tension. In the early years of production, the engine was equipped with too thin unreliable valve springs

Chain tensioner doesn't fail, it leaks down at the secondary tensioners for the cam to cam chains and only causes a slight start up rattle. No long term damage or issue except annoyance unlike the UZ blowing out its cam seals and soaking the belt in oil.
Also I'm not sure why you care so much about having a timing belt in a non-VVT version. You can snap it without killing valves.
The UR makes over 100 hp more than the UZ and gets better mpg doing it, breaks less, is easier to work on and having owned both there is no comparison. How many URs have you owned?

It's actually because people are scared of redline and using the power, I've yet to have a single one persist even when they are as bad a a quart every 300-400 miles. The less severe cases can literally be as easy as a few max power runs back to back

. The older Toyota stuff is better than the newer stuff.
Your 2UR was never updated
…it’s the same as it was in 2006. Where is the innovation? At least with the 2UZ it was updated mid cycle. (Even though the stuff they added is not cool in my books)

You're against VVT-I? It really livened at least the LX570 up. I too love the 2UZ but it's not exactly bursting with power. I blew a first gen Sequoyiah away with the UZ in my old 5.3 Yukon, not even close.

I should have been more clear. Toyota's documentation states that, but there are literally hundreds of cases of pre-VVT engines that have snapped their belts (often at highway speeds) and suffered no damage. Here's just one example:
Every "forcible valve re-clearancing" failure I've ever heard of has been on a VVTi motor.
