The dealer has no authority to forgive your miles. When the dealer tells a customer they are forgiving your extra miles, they are actually just transferring the cost to your new lease. Trust me, you are paying for the miles. It's a shell game.
Miles are. 20 if purchased prior to 4 months before lease end and .25 after that.
You can buy them online directly through BMW FS. It takes all of 5 minutes. Do not go through the dealer unless you prefer to pay them extra profits.
