There is oil. But its sealed up meaning you cant check it or fill it, either a dealer of mechanic can do it. I think the oil lasts 100k but dont quote me.

i'm in So Cal, and i've been letting it idle untill the temp needle moves at least a little bit, just an old habit i picked up from the vette.

I think polluting is the least of any auto enthusiast's concern.

Not sure if there are any recommendations in the IS350 manual, but both IS300 and another prior car stated that warm-up is not required and you should start driving right away, but just take it easy. (similar to the break-in period). You can go 55+mph, just try not to mash the pedal.
I believe it stated that warm up is only recommended in extreme temperatures (I assume -20F or something).
Personally, if the temps are 20F+, I just start driving, if they are lower, I give the engine 30secs or so to circulate the oil and make a slow start.
I also try to use synthetic oil after the initial break-in period.

Just curious if anyone warms up there car in the morning before driving of.

I always think maybe I should warm up the car before driving but I am always late in the morning so I usually just end up driving of right after starting the car. Is it important to warm up a car first. I guess it would depend on the outside temperature too.

Just curious thanks.

I would if it was cold where I live
When I lived in Brooklyn I used to warm it up until the tack on oil temperature was off the C(cold).

in California, i don't think it is necessary to warm up. just take it easy until the engine is up to operating temperture.
