I have 2 kids and a dog. The kids love the wagon... I also have a 914 Porsche, a blown 84 mustang, and some really fast bikes!!!
The reality is that I need a family car for trips and such, but I still wanted it to handle well and be a little fast than most cars on the road...you know, like SVTs?
Speed is only a matter of money; how fast do you want to go?
