A vehicle loses value, burns fuel, and sends you a
service bill every year. This totals all three — per kilometre, on depreciation
curves measured from actual PL listings.

The big one
What it bleeds while you own it
The orange line is the real value curve for this class (smoothed
from PL private-seller listings). The shaded band is your hold window — buy on
the left dot, sell on the right. The gap between them is depreciation: usually
the largest single cost of owning a bike, and the one no dealer prints on the
tag.

Buy in February, sell in May
Prices swing with the season — a bike costs more in spring than in winter.
The panel opens when the tracker has twelve months of data. Then: cheapest
month to buy, dearest to sell, and the złoty timing alone saves on top of the
curve.

How to read this
It's a band, not a verdict
Three caveats
Depreciation is ours; the rest is modelled. The value curve is
real data. Fuel, the service/wear reserve and fees are coefficient estimates
— that's why we show the yearly figure as a range, swung by the wear
reserve.
Insurance is yours. We refuse to guess it — paste a real OC/AC
quote and the receipt updates. The default is only a placeholder.
Resale assumes an average example. Your bike's condition, mileage
and history move the sell value off the curve. Treat the end value as the
midpoint of a fleet, not a promise.
