How these prices work
Based on 176 used listings from the past 12 months, including ones that have since sold or ended. These are asking prices, not final sale prices. Each listing counts once, at its latest price, and unusually high or low prices are left out.
Typical price: half the listings were priced below this, and half above.
Most listed between: the middle half of listings fall in this range.
