I've always worked on my own cars unless the issue is beyond the tools I have. I am hoping to do the same with my RX. Bought it new so no issues yet (until two weeks ago) so other than changing oil and the various filters, fluids, air pressure, there hasn't been much to do. My other cars are Toyotas and I have the shop manuals for those. I don't see that Lexus shop manuals are readily available so my first question would be how do I get a decent shop manual? Thanks.
