On the money for the kids, bare trusts are used to avail of the annual gift exemption of up to €3,000 per person to anybody else. The policy is set up in the child's name, under trust. You gift them €3,000 a year and it doesn't come out of future inheritance. The way you are doing it now, if you gave them €50,000 in the future, for example, they have to notify the Revenue and their future inheritance is reduced by that amount.
If you want to use the money you are saving for college, there is no need to have a trust, parents can pay for their children's education. Weddings are also exempt as they are seen as a family event. You'd be fine with a car too as it is probably a few grand and the Revenue aren't going spend the time and effort going after all the parents who bought their kids a cheap Suzuki Swift!
You are better off however, investing it in the markets so it will generate a decent return above inflation in the long term. Keeping it on deposit will most likely see the real value of the money fall over time.
