FWIW, I've got a wife that's actually really good about cars. She got a little funny at one point (kinda insinuating that the girls are looking to pick me up etc. Ironic, cause there aren't really any girls around when I'm talking cars - on top of that, I'm a pretty ugly guy). So I fixed her. Brought her along on a couple of parts pick up and sales; also a "come over an give me a hand with putting this part on" trip. She got to stand in the corner bored as hell while I talked cars for hours.

All set.
