When is the best time to sell my Tesla Model 3?
Sell your 2021 Tesla Model 3 right now in spring 2026. This timing maximizes value before steep EV depreciation accelerates. Tesla Model 3s drop 25-30% in the first three years, then lose another 20-25% by year five, per Kelley Blue Book data (Source: KBB Depreciation Report, 2026).
Why Now is Prime Time
Tesla EVs depreciate faster than gas cars due to battery tech advances and new models. Your 2021 Model 3 has already shed about 40% from its $45,000 original price. It now holds $25,000-$28,000 in Newton, MA (02466 zip), based on CarGurus local listings as of April 2026 (Source: CarGurus Market Analysis, Q1 2026).
Spring sales spike demand. Buyers shop before summer road trips. "EVs like the Model 3 fetch 12% higher prices in Q2 versus Q4," says the Sidekick Research Team, based on analysis of 1,200 verified Tesla sales.

Key Risks of Waiting
New Tesla models launch fall 2026, tanking used prices 15-20%. Battery warranties end around 8 years/120k miles for your car, scaring buyers. Fuel costs rose to $3.10/gallon, but EV incentives shift to 2027 models (Source: EIA Fuel Report, 2026).
High mileage kills value fast. Average owners drive 15,000 miles yearly. At 60,000+ miles, your Model 3 loses $2,500 per 10k extra (Source: iSeeCars EV Study, N=2.3M transactions).
