Your going to be putting extra miles on it when you drive it home. Why did you buy it so far away. I read some place not to drive a vehicle at the same rate of speed for long periods of time during the break-in period.
Because he got it an invoice!
As to the "break in" period, most say the first 1000 miles is the break in period so avoid cruise and have some fluctuation in your speed. And then consider an oil change at 1000 miles. I'm sure he's avoiding the cruise and fluctuating his speed frequently lol!
