As a present to your new husband, I think it will be truly appreciated. The others are all looking at this as a present to another couple, not from the wife to her husband. If he is a car nut and will probably like most of us regular people never be able to drive such a car then the experience will be one he truly appreciates, I think. I think experiences can be much more appreciated and enjoyed and remembered then getting "stuff" Stuff tends to get obsolete, or break, or you just don't really need it, but great experiences you will remember for a lifetime.
