Well, I'm sure you've considered:

1. What it does to the value of the car.
2. The car's future (how long you intent to keep it)
3. How difficult it will be to replace it if you decide to you liked it better the way it was.
4. ...and how much better it will look with the scoop.

In the end, it's obviously your call. Write down all the pros and cons, and go with your gut. Like everything else, you'll have to live your decision...and your car.
