A previous car of mine was bought with misleading badges, so it claimed to be something it wasn't.
When I first got it, I didn't even realise what it was claiming to be, then I did, and had no problem with that. It also had a kit fitted to it that was prestigious, but was not advertised, and I had no problem with that..
Most of the time, I'm not using the performance of the car, so claiming to have more was not an issue.
I plan to debadge the A4; those who know will not need the badge, and those who don't can imagine it to be better than it is.
It's a little bit like telling people you have a secret; someone else having one, no matter how small, can be irksome, so have one yourself, and ensure you have a chance to give them irk back! Because whilst you are an expert in your own car model, do you really know all the combinations of the other cars in the Audi range, across all sorts of models? Really?
And if someone fits wheels off a different model, do you feel the urge to deride them? How much of that car do they have to fit to be "entitled" to a badge off it? Wheels? RARB? Grill? Bumper? Steering wheel? Fuel economy? Performance?
No, feel free, if a bit of chrome and red will improve the image for you of your car, fit it and enjoy it. In the end, as long as you clean it and then stand back to enjoy, look back at it, or enjoy looking at it as you walk up to it, then the styling of the car pleases you, and that is what matters.
