Thunderbird Formula 270 SUN Sport keeps an estimated 55% of its value after 5 years — #5712 of 5915 boats VINdown tracks. See its full depreciation curve, cost per day, and best model year to buy.
Per VINdown's modeling, the Thunderbird Formula 270 SUN Sport retains an estimated 55% of its value after five years, ranking #5712 of 5915 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 270 SUN Sport sheds about 9% of its value in year one alone. From roughly $194,820 it falls to around $106,566 by year five — a five-year loss near $88,254, about $48.36 a day in depreciation.
Because the steepest drop hits around year 3, a lightly-used Thunderbird Formula 270 SUN Sport bought at 3 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
