Well I've got four kids, and all during their growing years I have had Street Rods and sports cars. They just took turns in the cars.
My wife and I went off to lunch when the kids were at school.
Kristen 'hey,littlecobra' over on the Texas site would possibly chime in here, as she has a few kids and the Cobra is hers to get away at anytime.
Now let me say the older the kids get, the more expensive they become. They are always yours and always need your help.
Good luck with what ever decision you make.
