I just returned from an 870 mile trip up to northern Wisconsin and my TL-S ran great. Road speeds were mostly 75 to 80 mph on the open highway using cruise control. Most surprising of all was the average gas mileage for the entire trip. I averaged 28.95 miles per gallon overall even though I got up to 90/95 in a few passing situations on two lane roads. This baby really hauls! Not one rattle or squeek, or any rock chips, thank god. Gotta love this silver TL-S!
