I agree with zed. Go test drive them all. Focus on practicality. Is the suspension too firm? Is ingress/egress manageable? Storage space? Keep an eye on those things in addition to fun/solid to drive.

I just picked up a evo 10 last month and love it. I actually like driving it more then my boosted z believe it or not. The steering feel is amazing , s-awd is insane in the corners and I can floor it without fear of being arrested. I got a matching recaro baby seat . I got a DVD in mine and my daughter loves it (2yrd) I also can drive it in any weather and drive it hard without fear. Mine doest have any build quality issues at all, everything is nice and tight . I can't wait for the first snow:driving:

get a BMW 3 series or g37 sedan.

If you really want a family hauler, then pick up an Accord, Camry, Sonata, Malibu, Mazda6, etc. These cars can be had for the sub 20k. Why do you have to get rid of one to get the other? In addition, going to a STI or Evo as a family hauler is a stupid idea. These are performance cars, not family haulers.

Yah id do the G37C or the sedan with 6MT if that was the only choice.

Or get a used car and use that for daily tasks, keep the Z?
