People.... When did he say the minivan is unreliable (which elicited two posts)... he says the Caddy must stay and you guys say "trade in the caddy", he says the wife will not drive a stick and you guys say "teach her to drive stick"... he says no M5 and you guys say "look at the M3 too".
IS ANYONE READING GOTTSPD's POSTS?!!!
GOTTSPD, I must say... first of all I think that your wife must be a confident woman to be totally fine with the minivan and not need something to appear "cool" with.
So really, the problem is not hers, its really more yours. You are upset of having an NSX that sits there a lot.
To me its simple. The minivan is her car... and she is fine with it. The Caddy is your daily driver, and you are fine with that.
As far as the baby, the baby is fine in either car, when you take the van either parent can drive, when you take the caddy you have to drive.
You see, there really is no problem here, but the one you are creating in your head. That is, here is an NSX that sits a lot. So the question is... should you do something about that? If you want to go to the track, the answer is a definite NO. If this is going to be a third car, which it is, what better car to have than a reliable, low maintenance, zero depreciation, sexy looking NSX.
No, your wife can't drive it. She doesn't seem to care. All three of you can't take it on a trip... you have two other cars that do that. The baby seat doesn't allow work lunches... so what... its your third car.. the track car... the toy. Something has to give with it being that.
So really the answer to me, is to do nothing. Not unless your wife has come to you and said "honey I want a more fun car". The minivan is certainly a safe car. An excellent choice for a mom that cares about her baby. She didn't come to you like many other women that need to feel cool and ask for an unsafe gas guzzling SUV instead. She is comfortable with who she is.
You are lucky to have her, a cute baby, and an NSX. Really if you are getting bored with the car, I suggest you sign up and start going to the track rather than spending your energy on finding a different car.
