People fall into "lust", not love..... I personally don't know what that's like. And will ride out into the sunset not know and that's OK. If you figured out the love and not lust equation you have a solid life partner.... It means you both pull the Wagon in the same direction.....
As for the OP, I have seen this work or maybe even tolerated at best. I personally have never met a woman who didn't enjoy being around an older car at some level. Maybe you can figure out a part of your hobby that would flip her trigger.... Just thinking out loud for you....
