The Lionel body shell is pretty decent I do admit but my 63 year old eyes can tell the difference between My Overland and my Lionel SD70ACes from 25+ feet away without trying. The 3' too short wheelbase and 4' too short fuel tank are dead giveaways. I got rid of my MTH SD70ACes because they were, well, just wrong.
On the other hand when it comes to paint blue is blue and red is red.
