Sorry Ernie, I lumped you in with BinB - my mistake and I apologize. After I re-read your post I see that you didn't make a dumb comment this time!
Actually I don't have a CSX car - I have a Kirkham.

I think that the newer aluminum bodies (different alloy and thicker) are way more dent proof than the originals but that the reputation for denting that aluminum has, still follows it around.
I would have no problem with someone pushing my car in the same way as they pushed my ERA - usually around the tail light area.
I have spent many hours - believe me!- working on my car and leaning on the fenders with no adverse results. Not saying that aluminum is dent proof nowadays, but it ain't as bad as some would make out.
I did lower the car a little too quickly one night - and it came down onto the handle of the floor jack.....dented the aluminum. If this were a glass car the glass wold have cracked for sure. Instead is was $90 to Dent-Pro and it is good to go.
I also had a retractable extension cord get away - hit the rear fender! Dented same. I don't think that glass would have dented.
