Porsche 718 Cayman and Boxster
$70,000-$150,000
Can You Write Off Porsche 718 Cayman and Boxster?
Short answer: Partly: a two-seat sports car is hard to justify as mostly business, and it's capped like any passenger car.
Under 6,000 lbs GVWR it's a passenger car, so first-year depreciation is capped at roughly $20,000 with bonus depreciation for 2026, and only the business-use share counts; the 72.5¢ mileage rate is the simpler option.
Records to keep: Keep the purchase contract, the door-jamb GVWR sticker photo, and a mileage log showing business vs personal miles.
