The median 2008 Boxster in the Canadian market sits at $29,900. That's your anchor. If a seller is asking well above it, the extra needs a reason you can see in the car, not just in the ad copy.
Most cars land between $29,638 and $32,996. That's a tight band, only about $3,400 wide, so there isn't a lot of room to argue price on condition alone. A car priced at the bottom of that range is closer to typical than to a bargain. Anything under $29,638 is where you'd want to look harder at history and service records before you get excited.
What the mileage tells you
The typical 2008 Boxster has around 87,587 km on it. That's your reference odometer for this year. A car sitting well below that number can reasonably command the top of the range, and one running well past it should be pulling toward the bottom. Use 87,587 as the line you measure any listing against.
We've flagged one deal on this model year in the last 90 days. These don't come up often at a price worth acting on, so when the numbers line up, it's worth a closer look rather than assuming the next one is around the corner.
