The 2012 Lexus RX sits at a median of $13,244 in the Canadian market right now. That's your anchor. If a seller is asking well above it without a clear reason, you've got room to push back.
Most listings land between $11,936 and $14,696. Think of that band as the normal zone. A well-kept example near the top makes sense, and anything under $12,000 is worth a hard look at why it's cheaper. Below the bottom of that range, start asking questions before you get excited.
What the mileage tells you
The typical 2012 RX on the market has about 194,000 km on it. That's a lot of road, and it's baked into the median price already. So a car sitting right at $13,244 is what you'd expect for one that's covered close to 194,000 km. A lower-odometer example earns a spot at the upper end of the range. A much higher one should come in cheaper.
Four of these got flagged as deals in the last 90 days. Not a flood, but enough that a fair price does turn up if you're patient. Use the $13,244 median and the $11,936 to $14,696 range as your check, and let a car's actual odometer reading tell you where in that band it belongs.
