Thanks for the review! Yes there is a reason for those miles as we test drive a vehicle before and after we perform transmission and cooling system services to ensure that there are no problems. We also work to make sure the transmission shifts properly during several test drives after our service. For this type of service we typically drive a six-mile test loop that includes stop-and-go driving as well as highway speeds. We are pleased that you like our work! It's a pleasure doing business with you!
