Don't know why you guys feel like you have to give up your cars because you have kids. If your looking at $40k cars, then you should be able to afford a $2500-$4000 four door for the family. I have two boys, 23, 9 and I've never at any point given up any car that I've had or not gotten one I wanted. Granted, my family car is a 465hp SRT8
I'd still buy a reliable beater to get around in before I got rid of my Nismo.
