Wow... my 87 S4 5 speed has several of those jacking dents. I am kinda amazed though at why those dents happen, my 87 was sold in Montreal, and one of the previous owners was a member of the PCA (there is a PCA sticker on the hatch glass). Is it that hard to just disperse the weight more evenly with a long (1 ft) block of 2" thick hardwood on top of the jack when you jack it up? To me this would not produce any dents... unless you set the car down on jackstands that are also located there, but i use the external-most 2 jack points when positioning jackstands.
I've done it. The floor still deflects. Doesn't take many reps in cold weather to break the bond between the floor and the hexaganol patterned sound insulation layer. There are no good reasons for using the rails as lift or support points.
EDIT ---- The external-most 4 jack points are where the jackstands need to go. 17, where are you putting the jackstands, if not there? Not to hijack, but these are a hassle to lift and not intuitive, so consider doing a search on this / be certain your method is safe.

Didn't Constantine once post about a method of straightening out the dents in the floor rails ?
IIRC Involved cutting a slot to insert a piece of steel plate just smaller than the box section into the box section, then drilling holes above the dents to bash them out downwards using a punch through the hole onto the steel plate, assisted by G clamps around the rail from below to push sides of the box section back to vertical.

Oh no!
I got a bent frame too!
How can I have bought a car with a bent frame? Can't beleive I did that.
Now, the only thing to do is looking for another car.
Won't be easy to find somebody to buy mine though.
...But I love my Cobalt Blue S4.
Maybe I can try to live with that...
On a more seroius note, I'm sure you will find somebody else to buy your car.
Somebody who will be wise enough make the difference between a bent frame and a nice car!
Good luck with the sale.

Maybe this sale can be saved with a follow-up conversation between the "928 guy" and the potential buyer to clarify what exactly he meant when he said that the car was "bent"? 
I'm certain the three PO's of my car each took turns at bending my frame...

When I purchased/installed my US made 2 post asymmetric lift for my new hobby garage, for kicks, I looked at the instruction manual for where to lift various cars. GUESS where the front lift points were specified for a Porsche 928!
YEP - inboard from the actual lift points, and right at the area where the compression channels are located.
SO - it isn't JUST the shop guys who are at fault for the damage we see on these channels, but actually some/many of the lift manufacturers as well.

PS: The arms on this asymmetric lift work perfectly for the four lift points on a 928!

Many times 928 "experts" are just not at all acquainted with the cars even though someone in the shop may have successfully worked on one. Even people here suggest places that are later found to be just run of the mill shops that maybe can read a manual page it two when they get confused.

Who knows how many bent frames I have been responsible for. When I was in highschool learning on cars I jacked up a beetle (I think) using the oil pan. It burst and sprayed oil all over the floor. Pretty sure I **** my pants.

That's what I am saying. People own these cars, work on them for money, even as a mechanic. But you really have to have an interest in learning the ins and outs, and most mechanics simply are not in that business. Owning 928s and working on them on a long-term basis are two very different things in my mind.
