2001 Rx300 engine codes
I've got a Rx300 with 236,000 miles and the CEL keeps coming on. I borrowed a reader and the error codes are P0325 Knock Sensor Bank 1 and P1349 VVT Malfunction Bank 1. Does anyone know how much ballpark it would take to have the mechanic change our the knock sensor. Does it seem like that could be throwing the other 1349 code as well. When this happens you can tell the engine does not idle properly and obviously acts weird in 'limp' mode. When is it time to call it quits on this old car?

Welcome to Club Lexus
When it comes to old cars it helps if you have some skills or have a friend who does.
Knock sensor replacement can be expensive because of where they are located. The VVT is easy to get at but still probably $150-$200 to have done.
If doing things yourself and looking to minimize costs, the knock sensor can be hacked and a the VVT screen can be cleaned to see if that fixes the VVT issue. There are threads for both of these.

Welcome to ClubLexus.
To get real info, pick up the phone and call local repair shops. Make sure you ask for parts and labor break down. There are two hacks and also a proper fix. Make sure you insist on small harness replacement. Might as well throw in the coolant replacement.
When should you give up on your current RX is an answer that you have to determine. It really depends upon the current condition and your need. Make sure you include the upcoming expense. First gen does not have the latest convenience things built in, but as a basic vehicle it is fairly sound. Unlucky owners have had transmission issues, but other than that, it is basically use/wear items [battery, tires, pads, plugs, lower control arms, oil]. Looks, reliability, comfort are all present. Lexus only guaranteed 60K miles. I would have kept mine had it not been totaled.
