I personally will help my kid(s) find the appropriate vehicle when the time comes (including proper instruction at a professional driving school course beforehand), but it will be up to them to purchase (the Wife & I will go as far as a small loan perhaps), insure, maintain the vehicle etc.
I feel they will appreciate the car (and responsibility in general) more that way when they have something to work for rather than just giving/buying the kid their own vehicle......just my 2 cents. :) Enjoy!
