INSPECTION DETAILS - J. ROAD TEST
A comprehensive road test is vital in order to ensure that a perfect automobile is delivered to a Lexus
customer. We recommend that you map out a specific road test course that includes a variety of road
conditions including stop and go, highway speed and rough road surfaces. This will help you check for
squeaks, rattles, drifts, pulls and a variety of other conditions that must be corrected prior to delivery.
NOTE:
Make sure protective covers are in place on the seats and carpet prior to starting the road test.
