Should I buy a 2021 Tesla Model 3 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 32.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.9% — always verify the vehicle history report.
• Price trend: Prices are up 3.13% year-over-year.
• Owners rate it 4.61/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of owner satisfaction, pricing context, and inventory depth, the 2021 is a sensible primary target. If you’re more price-sensitive, you can also compare nearby years to see whether a lower asking price outweighs the 2021’s stronger market position and broad appeal.
