The median 2009 BMW Z4 in the Canadian market sits at $24,900. That's your anchor. If someone's asking well above or below it, you want a reason before you keep reading the ad.
Most of these cars land between $23,250 and $27,849. So a fair chunk of the spread is only about $4,600 wide, which tells you the market has a pretty settled opinion on what this car is worth. Anything under $23,250 is worth a hard look, either a genuine deal or a car with a story. Above $27,849 you're paying for something specific, low kilometres, a loaded example, or an optimistic seller.
What the kilometres tell you
The typical 2009 Z4 out there has about 95,000 km on it. That's the mileage baked into the $24,900 median, so when you see a listing at that price, assume it's carrying roughly that much wear unless the ad says otherwise. A car with 60,000 km should command more than the median. One pushing past 130,000 should come in under it.
We've flagged 3 deals on this model year in the last 90 days. Not a flood, but enough that priced-right cars do surface. If you're patient and you know the $24,900 median cold, you'll recognize one when it shows up.
