Considering Replacing 2009 RX 350 with a 2013 RX 450h Premium — Is It Worth $19K?

Hey everyone, I’m looking for some input on whether to make this upgrade. Here’s the situation:

I’ve got a 2009 Lexus RX 350 with 177K miles, but it’s currently not running and needs a mechanic to diagnose the issue. It’s got some wear and tear, but otherwise it’s been reliable until now.

In contrast, I have the chance to buy a 2013 Lexus RX 450h Premium with relatively low mileage (around 80K miles). It’s been garage-kept, mostly driven by a grandmother, and is in excellent shape with new tires and a fresh standard battery. Everything looks pristine.

My main hesitation is about the hybrid battery life and whether that’s a concern down the line. The seller is asking $19,000.

I’m trying to figure out if this is a good deal given the condition and the upgrade.

Should I buy it?
