I’ve gone over by 12000 miles before, and waited 3 months extra for a new car, wasn’t asked to pay anything for the extra 12k miles.
Two leases later my mileage has steadily dropped year on year, current car, 37 months so far (Ioniq 5 on order) is only on 43k miles. Next car will struggle to top 30k I think.
In life, it's not who you know that's important, it's how your wife found out.
