Should I buy a 2018 Porsche Cayenne or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 28.0% of listings are priced as good or great deals.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want a Cayenne that combines strong performance, a refined cabin, and stable pricing, the 2018 is a sensible target.
