Good on you, i've a mk1 as well and yes i spent a very long time trying to source a grille, they are virtually non existent in the UK. My grille looked a lot worse than yours though, about a third of it was missing after i had a knock in it.
It took me a while to bond with the safrane, like you i had no real desire to own before before i got mine, it came along by chance but recently i have really grown to enjoy the cars comfort and i reckon they will look better with age so my cars going to be a keeper.
PS theres a reasonably priced mk1 parcel shelf on ebay at the moment, be quick its the only one!!:
