If you own a new car it is better not to mess with it, as you could affect the warranty on the car.
It does not take much for the dealership to say, that is no longer covered by warranty.
Once the car is out of warranty, then its up to you, what you want to do with the car regarding modifications.
After saying that, I remember when I bought my first brand new car after many old secondhand cars, it was a Toyota Celica ST MK1, and in the first month of ownership, I cut the metal roof open to fit a rectangular sun roof with hinged glass. Good job it turned out rainproof as I used a tin of Gas Turbine sealant which I got from my work. That stuff sealed anything >
