Hulkster,
I know that you haven't been married long with this statement - "and i would say "yeah thats nice, but does it have a bonus room big enough for my showcase cab?""
You can't do that. It's like if she ever asks you "Does this make me look fat" You better say "no, dear".
If she wants a house that doesn't have the room you want, then make fun of the bathrooms or the kitchen.
