I don't think the cost of maintenance, per se, is going to be that much more, if any more, for driving faster. If I drive 100 miles @ 70 mph instead of 55, the driveline still went around the same number of times, the pistons went up and down the same number of times, the tires went around the same number of times, etc. Since we do our oil and filter changes, etc, based on miles driven (or at least we're suposed to), we will pay the same amount for these items at either speed.
