40 is not too old to own a civic. No one is ever too old to own a civic. I see grandma's and grandpa's driving them all the time, although they're stock. My dad is 49 and he likes driving my civic (99 Civic EX). He normally drives his pick up truck around and when he drives my car, he tells me that he likes it. Why? Because it's so damn light and you can mash the gears up to pretty high rpm. Not like you can do that in a heavyass truck.

Anyway, I thought about selling my civic and getting something bigger too, like a Lexus or Benz or something all hooked up. I am barely 19 and even thought about this. When I sit and think about it, I don't wanna get rid of the civic. It's great on gas, not too pricey to maintain, and it's fun. Getting a luxury car or whatever is EXPENSIVE, but if you wanna go for the luxury/comfort, the choice is yours. That's why I was indecisive.

But yeah, the choice is yours. If you wanna get a civic, get it. I think you would love it as you already love your wife's.
