The primed side moldings are now £40 each for the fronts and £29 each for the rears as I bought mine not long back.
You obviously need all the top parts as there the 2 skirts and 4 jacking point covers...so these
MO 853 853 D GRU Left Side Skirt Primed £24.30
1M0 853 854 D GRU Right Side Skirt Primed £24.30
1M0 854 927 B GRU Insert Cover Primed £2.90
1M0 854 928 B GRU Insert Cover Primed £2.90
1M0 853 917 B GRU Insert Cover Primed £2.90
1M0 853 918 B GRU Insert Cover Primed £2.90
I'm not sure what the other part numbers are without seeing the parts.
The bottom two are just screws and clips, if you want correct torrix headed screws get genuine ones, if you don't mind black pan heads [you can't see most of them anyway there under the car] get them from motor factors and save a few quid.
I hope this makes sense.....its really hard to tell what you need just by part numbers and quantities but basically if your going to the garage get the exploded diagram up and you want....
2 skirts
4 jacking point covers
The genuine clips that fix top of skirts to top of sill [to be stuck on]
The genuine clips for bottom that screw into floor + skirt [be sensible, use short screws and seal to stop going rusty]
Some spire speed clips and screws to hold bottom clips to skirt + car.
Something double sided to stick top clips on
I expect it will come to about £200
