Nah i debadged it myself. I had asked the dealer about it. The sales guy said that the cars actually come with Opel badges (I. KNOW!). When i requested that they get left on, he said it was a contract they had with Holden that they had to remove and destroy the badges and then rebadge with a holden set.
If you're wondering how to debadge it it's really easy:
1. Leave your car in the sun for a bit so the glue warms up a little. The longer the better. I left it for 10 minutes and it was...ok.
2. Get some dental floss - do a few loops of this because 1 line isn't strong enought.
3. Just stick it between the badge and the surface and just "sawing" away at the glue until it finally peels off.
4. Clean and polish. They'll be some black gunk on the surface after. Just peel and peel and peel and it should come off easy. Little speck remains I just used some surface cleaner and it came right off.
Don't know if thats the BEST method but it worked for me
