I have a srt6 as my second car. There is absolutely no way I would recommend one as a first car.
Would I have wanted one? Absolutely. But having just the few years of experience to look back, I definitely didn't need one.
My advice, quit looking at nice cars for a first one. Depending on the money supply, go get something decent, but don't bother getting something very very nice because statistically speaking, there is a good chance you will wreck it. I believe it's 2/3 people get in a wreck between 16 and 18.
And I know, "I won't wreck it." I said the same thing, I'm sure we all did. I did wreck my first car (99 monte carlo) It wasn't bad, I ran over a powerbox on the side of the road. Barely anything happened to the car, just a 1" crack in the bumper, but it did cost me 2 grand to pay for damages to the box.
My 99 monte carlo was an awesome first car. Enough power, but not too much. I drive fast, still do, but what I didn't know when I was new at it was where I could drive fast. I just drove fast everywhere. That finally caught up to me when I was driving through a neighborhood and came around a corner to a car coming out of a driveway. I had to brake hard, which of course doesn't do good things to a big car in a corner. After swerving back and forth, I came to rest on that power box.
I can confidently say that I would have destroyed my crossfire if I hadn't learned to drive something else before it. Getting into traffic for example. Floor it too much in the monte carlo may spin the tires and twitch the car a bit, it'll get your attention but not a big deal. Do that in the srt6, and you may whip the back end out, causing all kinds of possible problems. And even that, I can correct it if the back end comes loose around a corner (to a point obviously) but had I just started, I almost certainly wouldn't have been able to.
Don't get this much power for your first car, and hopefully your dad knows better than to let you. Learn to drive for a while, then you can look into getting some power.
Not knocking you here at all, just speaking from what little experience I have. I'm sure others here with much more experience will say the same.
