Yes, it is $700 each to have Europa bumpers re-plated at the only remaining shop in Nevada.
I was told that in CA it would be nearly double that. 
I left a nearly strait front to be done for my own car.
I already have a never mounted since re-plated rear.
Now the question is, at $1,400 a set.
Will newly plated bumpers increase the value of a mechanically tidy S2 still in need of paint by more than the expense?
Lesser options include a "Chrome" wrap or powder painting.
My experience with powder paint is that it looks too much like aluminum and scuffs too easily.
Not sure a wrap last well enough.
Thoughts?
Depends.
Chrome plating is a dirty, environmentally unfriendly process. You're not paying for, necessarily, the cost of the metals but the heavy hand of state and federal regulations covering the control of heavy metal polllution, waste disposal, health and welfare of the workers, etc.
Is it worth it? $700 per is about what I paid 15 years ago. I know I spent, all in, in 2008, about $2100 to do the two bumpers, headlight rings, tail light bases (european) and door handles for 693R. Was it worth it? That's not the point if you're going to the extreme of replating door handles. It was shipwright's disease on steroids once I started down that road.
For a driver? You know, I'd have the darn things buffed down to get them smooth and chrome wrapped. Cost a heck of a lot less than going to a chrome shop.
Taking her to Pebble Beach? Spend the money.
In the end, only you can decide. I can say that for my TCS, the bumpers are in good condition, couple buff marks, but would probably polish out fine if I could find someone who did finish metal polishing!
