I can see the point some of you are trying to make, but I'd have to say "choosing looking good over your own childs safety" is a BS call. Its also just the type of fear perpetrated by car manufacturers, antibacterial bench top cleaners etc. which suits our consumerist culture so well. The worst drivers on the road are in NEW CARS hands down.
Having and maintaining old cars teaches kids good values imo compared to the majority of kids born with disposable spoons in their mouths.
While I'd have to agree that it might be a good idea to have a daily and keep the Datto for the weekend. For the reason alone that its OTHER people in NEWER cars are the biggest threat to your childs safety...I think the guilt trips are completely uncalled for.
