I'm looking for where I can go to download a pdf of both volumes of the OEM repair manuals for the 2001 Lexus LS430, does anyone know a website I can go to for this?

There is one set for sale on Amazon. Used to be cheap, no longer and they are really hard to come by.

The one set and only one set is $250.00 it is for a 2001. If you don't like it you can alway resale it.

I'd pay,

Also, I have a two book set for my 2002 and 2003. I had to look to see if I still had them. It is actually better and easier to use this web sight. Easier to follow and much better short cuts. Photos and videos do a better job than drawings.

I wasn't sure if this is still up but it is...

It's for 2003 to 2006 models but most things will apply to the 2001. Anything you're unsure of specific to your 2001 can likely be sorted out here on the forum.

A guy from South Korea on eBay sells service manuals in PDF for like $13.

I bought the Bishko replica ones (originals are out of print). You'd be hard-pressed to tell the difference.
They take up roughly 1' of shelf space (6 books).
You'd likely find that all this in pdf would be very difficult to navigate, particularly if you wanted several pages open at the same time.
