porsche911girl,
I was a high school teacher for 32 years and believe me when I say that, "I've seen it all" when it comes to mature and immature, responsible and spoiled. I might suggest that you show your maturity by ignoring some of the replies to your posts and continue asking questions on this forum.
I admire you for asking what other's think and the sign of a mature person is someone who is not not affraid to fail or be told is wrong.

The best advice I can give you is this. Jump off the cliff and free-fall for awhile. It's uncomfortable and a little dangerous, but you will learn things on the way down. This is only a metaphor now, don't go jump off a real cliff!!!!!
You are young and what better time to do this than now. I waited for 30 years to buy one of these great cars and I regret that I didn't do it when I was in my 20s instead of my 50's!
If you fail, so what? The best teacher in the world is failure. You won't always succeed at everything you do and that's OK. Safe, is not a very good teacher. A ship never discovered anything tied to the dock!
If you want to do this, and you can, DO IT! Take Grandma for the ride of her life! You will remember that for the rest of your life and smile and wave at your grandchildren someday from the inside of your Porsche 3000 911 Raptor.
The best of luck to you! Get those pictures on Monday!!!
