TBH, I've never been a fan of badge fever, the back of my cars have mostly been badgeless, although I do think the front tends to look odd without a badge.
Has anyone seen the back of a new Fiesta recently? There's hardly any room at all, yet they seem to fit sometimes 4 badges in the gaps. Ford, Fiesta, Titanium, TDCi, it drives me mad.
And for the record, for me anyway, it's got nothing to do with being embarassed or otherwise, I just think it invariably looks better. But that's just my opinion...
