Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 72% premium over grade-C stock, with grade-A medians at $155.

Fitment variant moves the price more than most buyers expect.

Confirm which variant your VIN requires before comparing quotes.

Model year matters too: 2015 units carry the lowest median at $86, while 2025 tops the table at $311. Parts from 2013–2015 are interchangeable, so if the 2015 fits your vehicle, it offers the best value across 3 compatible years.
