Rear Bumper Question

Rear Bumper Question
I came across an ad for a 1992 XJS coupe near me. I was thinking of checking it out since it's stored near another place I was going to go this weekend, but after doing a VIN search, I found that it had been listed on a XJS fan site with more pictures.
XJS Data - SAJNW5848NC181946 - Jaguar XJS information, articles, photos and register
Those bumpers aren't supposed to look like that, right? He must have gotten rear ended or something?

Found this on Wikipedia: "NHTSA amended the bumper standard in May 1982, halving the front and rear crash test speeds for 1983 and newer car bumpers from 5 miles per hour (8 km/h) to 2.5 miles per hour (4 km/h), and the corner crash test speeds from 3 miles per hour (5 km/h) to 1.5 miles per hour (2 km/h)."
So those infamous Big Bumpers weren't really needed from the early '80s then.
And it seems they were never about safety anyway - "The United States has focused on protecting consumers from repair costs, using government legislation."

Bent bumper tech dates back even before the "5 mph" stuff.
In older days, bumper shops did a steady business straightening and rechroming bent units to service collision shops.
They are made of steel an as such are malleable. So, they can be bent back in to shape.
Simple or complex.
Crinkled inwards, the fix is to pull it back. High quality chrome will stay affixed. Poor chrome will flake The simple fix.
Pulled outwards, not so simple. The bend is stretched metal. Shrinking techniques can fix that. Alas, they involve heat. There goes the chrome.
Replace or straighten and black in lieu of chrome???

From what I can see of the chrome it looks like it has been removed and replaced at some time. As a result the bolts that join the 3 pieces together(2 at each joint) have been overtightened. This is a common mistake and you see it a lot on cars that have been resprayed. The overtightening causes the joint to peak and look as above. Simple to fix if not a little time consuming.

It seems they were white for that model year:
"We once bought a whole car just for the '92-only white reflectors in the bumper," explains Mike Zavos, husband of '92 XJS owner Jennifer Hanson and the man charged with maintaining it. "The law changed for '93, and if we order that part number, we always end up with red ones.
