I definitely think these cars were acceptable without all the updates, but since you seem so eager to make them as accurate as possible, I hope you won't mind a little additional nitpicking:
- Reddick's Lenovo car should have an additional black stroke on the roof number, on the inside of the blue stroke.
- McDowell's car has the Love's logo and the Speedco logo both beside each other on the decklid.
Thank you again for sharing your talent!
