I think a man should be allowed to do whatever he wants to his own car. Think how boring life would be if we all drove identical cars?
Me personally, I think a Holden badge on the SS is fitting. (I've put Pontiac badges
on my SS-V Special Edition Commodore - factory Holden with Pontiac front)
But I would NEVER put a HSV badge on my car, or put an AMG badge on a stock Merc or M badge on a stock 4 cylinder BMW etc..
But, like I said, at the end of the day everyone has got the right to do whatever they want. If I or someone else doesn't agree, have a chuckle discreetly. Don't put a bloke down just because you have different taste to him....
