I am going to get serious in this post for once instead of kidding around.
I dont know what your overall financial situation is but I certainly hope this car is not coming at the expense of a good education. Pardon me for lecturing.. i dont mean to but I have seen from my own family's experience that at a young age people tend to think short term and think the good times with money rolling in will continue forever...
That car will likely be junk in ten years but good education in preparation for tomorrow will last a lifetime...
Thats my grandfatherly lecture for today!
