I have had a couple of people come up to me in the past on a night out who I haven't seen for years and they've gone "Oh, I've seen you driving around town a few times, you've got one of them Cupra's haven't you?".
The first thing I do is correct them and say "no, it's an FR" and when they ask what the difference is I tell them that it's the model down from the Cupra and it's a TDi. There's nothing at all wrong with having a car which isn't "top spec", I'm quite happy to admit that mine isn't. Yes, I'd love to own a cupra but the mileage I do really doesn't suit a petrol car.
I have Audi RS4 rims, that dosen't mean i wan't to own an Audi RS4, but the rims look cool okay, so take it easy and let the guy style HIS car the way he wants...
Personally, not to my taste, however you aren't claiming your car is an RS4 are you? If you stuck an RS4
badge on the back of your car then yes, it would be the same.
It's as bad at these guys who own a gold GT and glue an "i"
badge on, usually wonky and not the same font as the original haha!
