Example
For a current-rule Model 3 RWD delivered on June 5, 2025 with 10,000 miles, this estimator compares a four-year/50,000-mile Basic limit with an eight-year/100,000-mile Battery and Drive limit. If either time or mileage is already exhausted, that coverage is shown as Expired.
How it works
A rule is used only when its delivery-date range, model, and exact trim category safely match. The expiry date adds the published number of years to first delivery. Remaining days and miles are calculated independently, because the first limit ends coverage.
