On the 18 car, the siemens logo and the freightliner logo should be flip-floped, Interstate Batteries on the rear should be in lower case letters except for the I and the B, and John 3:16 was written below the left brake light in white ariel font w/ thin black outline. You nailed the base scheme and colors, looks really nice.
I had the John 3:16 on there already...but for somereason I had the layer turned off. Its nothing that a few minutes of fixing will fix today.
EDIT: Actaully after further review I had the right logo Interstate Batteries Logo on the rear, just the wrong one visible. Anywho the car is now uploaded correctly.
