What happens if I go over my lease mileage limit in NJ?

Excess mileage charges at lease end typically range from $0.15 to $0.25 per mile over the limit. On a 36-month lease with 5,000 excess miles, that’s $750–$1,250 due at turn-in. The best strategy is to negotiate the right mileage upfront — buying extra miles at lease signing costs less than paying overages at the end.
