Depreciation over the first five years is itemized in the cost breakdown. Luxury and EV models typically lose more value in early years; segment leaders and Toyota/Honda hold value better.

Question 4

Is the Mercedes-Benz GLS better than the Toyota Sienna?

Accepted Answer

It depends on how you drive. The compare page scores both vehicles across five pillars — cost of ownership, powertrain, driver assistance, livability, and safety — combined into one MotiveGrid Score, alongside a 5-year cost breakdown and a clear verdict. Pick the one whose strengths match how you actually use a car.

Question 5

Why do these two vehicles get different ADAS (driver-assist) scores?

Accepted Answer

Our ADAS scale weighs sensor stack (radar + camera vs camera-only), hands-free operating domain (highway vs any divided road), driver-monitoring quality (eye-tracking vs torque sensor), and whether the system gets OTA improvements. Two vehicles can advertise the same feature names and still score 20+ points apart once operating envelope and update cadence are accounted for.
