It is points down if the original parts can't be made to look as good as original in appearance .
Not always true. A chrome shop that specializes in antique car chrome work can "restore" the finish. My complaint is that they are sometimes too good, there is a deep blue "glow" that results.
When the old chrome is striped off they basically sand it loosing the crispness of all the edges.
That's one process, sand, that the shop I used doesn't employ harshly. It's mostly all chemical dips, more than 30 times in a dip of one nature or another, strip, rinse, plate, rinse, etc, with several steps of buffing as appropriate. Filling pits it the artistic part. Pot metal is difficult, but it can be done. You need to point out what you want done and what concerns you have, edges, recesses, flats, etc. I had my original 66 Rotunda mirror re-chromed, base and housing. It came out looking good (except for the deep blue - see above). The hardest part was reassembling the mirror and base, until I took apart a repro and reassembled it to find the "trick" (the long screw alignment). The cable ends were painted green, red and yellow, but the paint had flaked off over time. Testor's Model paint "restored" that feature. Fortunately for me, the interior control arm and plate were not in need of any work. I don't know the availability or quality of chrome shops in Europe, which may be your biggest problem.
