So I put my money where my mouth, er keyboard is and got one of each autorack:
Upon opening (which I took my time peeling the duplicate of the outer label seen above, off the inner clamshell), I noticed this typo. Can you see it?
Here's a view not seen yet--how the Menards autorack compares to the MTH Premier. Here I placed one of the two between a pair of the MTH cars. For a fair comparison, I picked two that have their trucks in the original position at the ends of the car. I may try to pose it with two newer cars whose trucks were moved inwards from the ends. Somehow the reduced wheelbase made those cars appear shorter in comparison with their older stablemates, despite being the same length.
As far as I'm concerned, they're a decent match. In a solid train of MTH autoracks one might not notice the length difference if you didn't know they were in the consist.
At eye level, the ride height is almost exact. Okay, the Menards cars' roofline is about 1/8" lower than the MTH. If rolling by in a consist, not really noticable if you didn't know it was there.
All in all, I'd get more if there were actual roadnames on them. I might still do so if I or someone else makes up suitable decals for the blank panel. I don't even feel a need to change the car number (the reporting marks are another thing I'd modify, but it wouldn't stop me from buying additional roadnames)
The blank panel measures 1 7/16" wide by 11/16" tall ( or 37x17mm) if anyone would like to take a stab at making up suitable railroad logos for these.
