Which Lexus models offer the best value on the used market?

Which Lexus models offer the best value on the used market right now, especially if I want something reliable without paying almost-new Lexus money?

Ive owned Toyota products for years and Im comfortable checking service history, looking for accident repairs, and dealing with normal maintenance, but Im having a harder time figuring out where the real value is with used Lexus models. The prices seem all over the place. Some older ES and RX examples are only a few thousand dollars less than newer ones, while certain IS models look cheap until I start reading about insurance costs, tires, carbon buildup, or neglected maintenance.

Im shopping in the Phoenix area with a budget of around $25,000, maybe $28,000 if the car is genuinely worth stretching for. My main use would be commuting about 40 miles a day, occasional highway trips, and carrying two adults plus luggage. I dont need something sporty, although I do like the idea of an IS or GS if the ownership costs arent ridiculous. An SUV would be useful, but I dont want to pay a big premium just because its an RX.

Right now Im looking at roughly 2016-2020 ES 350s, older GS 350s, RX 350s, and possibly an NX 300. Ive also seen good prices on higher-mileage LS models, but Im assuming thats a trap unless someone has a very convincing reason otherwise. Hybrid models are interesting too, though Im nervous about battery replacement costs as these cars get older.

For people who have actually bought and owned these, which models and model years give the best combination of purchase price, reliability, comfort, and reasonable repair costs? Are there specific engines or transmissions I should prioritize or avoid? Also, is it smarter to buy a higher-mileage Lexus with complete dealer records, or pay more for a lower-mileage one with less documentation? Im trying not to make an expensive mistake here...
