This engine is compact and energetic. It is mounted to a four-speed automatic transmission. The 300M has an AutoStick transmission so the driver can shift manually depending on conditions. In the hills around Fort Mountain State Park it was invaluable for positioning the car in turns or holding it in gear during steep descents. The cabin is genuinely spacious, both front and back.
Interior textures are soft and elegant looking.
An analog clock sits in an indention above the center outlets. While the auxiliary switches are much better than they were in the previous LHS, they fall somewhat short of some competitors in this near-luxury class. A small overhead console has a trip computer, compass and HomeLink transmitter. The front seats, with heat and power standard, are wide and generous. Ditto for the back.
