I get where you're coming from @DannyW, and to be honest now after the last 3 cars my wife just trusts me to know what she would and wouldn't like. I obviously show her a shortlist and get her to be involved in the test drive/purchase, but she's more than happy with what I recommend these days.
If she wants any further advise then she'll ask for it surely, without any need for trying to talk her into / out of specific cars.
