The genuine Renault 16V steering wheel center cover is not sporty IMO. I don't like it. I've made a custom center cap instead of it for my Willi. Some of my Hungarian friends asked me to do center caps for them. I've made a catalogue to make easy the choice. So I'd like to show this. If you'd like to order, please write here or pm me. All about the caps is in the pdf file.
