Minivan or station wagon with a rack - doesn't look like a contractor vehicle, reduces theft concerns, will handle a lot of tools and materials on the roof. Will haul the family without looking like your a poor smuck who can't afford to take care of his family.
Metris / Sprinter - works well, hauls a lot and not too big. Guys I know love theirs.
I've been in your situation and would suggest another route. I hauled my kids around in my contractor van for a while in the early days and hated it. Bad enough I made my kids work job sites and breathe crap. (Every child should have to work the job site, builds character, lets them know where the money comes from.) Didn't want them breathing crap on the weekends driving around. Doesn't matter how often you clean, there is always more sawdust or whatever dust in the vehicle. I also didn't like it because I felt like I was always working. Hey kids, the phone rang, time to do a service call after we have ice cream since all the tools are in the back.
Nice to tell a client you can't make it until monday since you are out with the kids in the car; rather than the client knowing you are driving your van with all the tools in it so coming by is no problem.
Finally decided to spend money on a nice vehicle for the family. Spent what I had to for a solid work vehicle that I could keep going for years. Always had two vehicles, 1 for family, 1 for work. I never looked as pretty as other contractors with their shiny trucks pulling up. Most clients didn't care, some clients were a little weirded out that I mostly had beater trucks. On a side note I've had somewhere around 70 vehicles at this point. A work vehicle is another tool. It should make money, not cost lots of money.
Another aspect to this is a work vehicle is a work vehicle. Didn't matter to me if the side got whacked by a 2x4. Guys who spent $30K+ on trucks always cried when it got dinged the first time. Eventually their shiny expensive truck turned into my beater. I knew a contractor who would get a new truck once his turned around 100K miles or so. He always had to have a newer truck, all shiny with all the options. Looking good was a big deal for him. He owed me at one point so he gave me one of his trucks around 120K miles. He thought it was a very unfair deal since the truck (in his opinion was on its last leg). He was one of those guys who still thought a vehicle was near death at around 100K miles. I finally got rid of it a dozen years later with 278K miles on it. It was ugly as sin, had a lot of quirks and my wife refused to get in it. Nonetheless it always started no matter what and never left me stranded. I tend to prefer a Ford but that was one great beater Chevy.
I don't know your situation, what kind of work you do or how much dough you bring in. If you are buying festool, you can't be too much of a poor smuck. I would suggest you seriously consider going two vehicle. Other guys I know that have done it were happy they did so. Also makes tracking deductions much easier. Get the ol' lady something nice. Get a decent truck and use it to make money. Obviously this is my own quirk. I have no problem with a car payment. A work truck payment, no chance in hell.
Good luck.
