Thunderbird Formula 31 PC keeps an estimated 55% of its value after 5 years — #5573 of 5780 boats VINdown tracks. See the full depreciation curve.
Per VINdown's modeling, the Thunderbird Formula 31 PC retains an estimated 55% of its value after five years, ranking #5573 of 5780 boats we track. That trails the 62% five-year average for Cruiser in its class by 7 points, so it depreciates faster than most rivals.
Most of the loss lands early: the Thunderbird Formula 31 PC sheds about 9% of its value in year one alone. From roughly $454,980 it falls to around $249,329 by year five — a five-year loss near $205,651, about $112.69 a day in depreciation.
Because the steepest drop hits around year 4, a lightly-used Thunderbird Formula 31 PC bought at 4 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
