As AK said. depends on your needs.
For me,,, I will get the 370z. Yes I am married. I dont have plans to have a kid for now. If my needs, during time changes, that probably will, because you never know what will happen next, I will consider, imo, a sporty SUV (used for sure), like an FX35
. But right now, I will definitively go for the 370z.
Always work by your needs and standards.
