Thanks for the answer Gryphon and lemon. :)
Where did you get the service manual lemon? Is it available for download or do I need to buy a hard copy?
I got my car back today :D. I stuck a digital camera under the car and snapped a few pics of the spokes on the rims from the inside and found these markings on each spoke:
--------
J DOT
35
--------
18x7J
--------
05/6
-------
Toyota B8
-------
Some weirdo symbol that looks like an oval with a lightning bolt through it and the number 3.
And a 2B stamped at and off angle (looks like a QC stamp).

I'm new to reading wheel markings but I'll gues the 18x7 and the 35mm offset is confirmed. Now to find some spare wheels at a reasonable price!
I'm glad for the law in Quebec about the winter tires, I think it makes the roads safer. I've had winter tires for all my cars for over 10 years.
Never regretted it and I don't think it costs more. Other than the marginal cost of rims and having them swapped twice a year (seasonal swaps are free if you get you tires from Costco), accidents could cost more, not to mention if it avoids any potential bodily harm to myself, my passengers or any one else, it's well worth the small price of rims. With this car, I'll need to get alloys though, they don't make rims in 18, and it would look not so great anyway with ugly black rims.
As for a new dealer, yeah, I was not impressed with the price but expected as much for Lexus OEM parts. So far, the service has not been stellar either. I bought the RX400H from them used. I don't expect it to be perfect but I expected them to do touch ups. They skipped on touch-ups, saying that touchups would show anyway, and gave me a touch up pen. <_<
The bumper was cracked and reglued by previous owner. They wouldn't fix it for free but I could not stand it so I paid to have it replaced and repainted, and the mirror was scuffed bad and had gobs of touch up paint on that so I paid to have that repainted too. The paint job was pretty lousy, there is lint stuck to the paint at various spots. They offered to redo the paint, but gah, I'd have to give the car up yet again for a few days. They offered to redo it on my next visit or when I next have some free time. We'll see how that works out. I need to find some time to yet again to take the car to the dealer and give it up a few more days.
