Mileage options on the website range from 5,000 annual mileage to 30,000, depending on the car. The differences in mileage will mean a difference in price. Every deal on Mega lease is completely unique to you, and you can choose your mileage based on your driving habits and how much you want to pay. If you go over your agreed mileage allowance, you will have additional costs so it would be best to think carefully about how many miles you will need. While for many of us it is difficult to calculate the specifics of exactly how many miles you are doing every year, be realistic about how many miles you may drive in a year, checking your previous mileage and how many you may drive in the next few years – Maybe add some extra miles for a safety net too.
