I think the Z is the best-looking, most-stylish vehicle on the market. Period. I get a big smile just looking at it sitting there. The smile only gets bigger when I drive it.
As much as I'd like to, I don't get anywhere near the same feeling looking at the new GT-R, but I understand that the GT-R is a fantastic performance vehicle, as nowadays many other vehicles produced by a variety of manufacturers also are.
You know your situation better than anyone on this forum. Just do what you think is best for your family but keep in mind that, as Joni Mitchell sang so many years ago, sometimes "you don't know what you've got til it's gone".
