Thanks for the feedback all.
I tried to go the custom route, but I don't drink and I've very little patience, so I went for Sonar ones.
The LHDs among us can buy them from a guy called Schmpa at seat-leon.de. He runs a
webshop over there.
I got the bumper cover back on this evening, so haven't had a chance to take daylight pics yet.
Guess I'll be able to take some pics tomorrow.
