I am looking to invest some savings and plan to use it when the kids get older. Kids are currently 4 - 7 - 10. I already have my 6 months of expenses, retirement, and college savings all funded. This money will be used for cars for the kids, misc college expenses, daughter's wedding, etc. I've been putting $50/week away for 2 years now, and it's just in a savings account. My thought is to move it to something with a better return. I use Vanguard for some of my other investments, so I was going to do the same with this one. A few days ago, I opened a Vanguard Star account and put 3000 in it to start this. Now, after a little more reading, I am having some second thoughts because of the tax implications. Would the VTSMX, total stock market index fund be a better fit?
