I'm 49 with 6 children, 4 girls 2 boys, Oldest 19 (girl) and youngest 7 (boy).
If I let my 13 year old son he would sleep in my Nova. I never miss a Lacrosse, Football or Soccer game that they play and as long as it's nice they will always say "let's take the Nova".
For the boys I think it is a very valuable lesson to teach them the love of an automobile and how to respect the power...... and most of all being responsible and knowing when and where it is safe to use the power while having fun. Inevitably you'll always here the young kids say "go fast" or do a burnout" the must be taught that there is a time and a place and a busy road or a neighborhood is not the place. Teach them now and with Gods help they will always hear your words just before they try something stupid and put themselves or others in harms way...... God willing!
