Well, as Patty says, and has stated here on the list aquite a while ago:
It's all about indoctrination - instruct your wife/husband/SO in the ways of
your interest and allow them to be a part of it and there is no need for
150% gifts :)

It worked for us. I had a Vanagon when we got together - I have since had 2
others and working on another. I've included her in everything (that she
wants to be included in) and it isn't much of an issue - we love camping
togehter and taking the bus on long rides.

A little while ago I said to her, "You know life without a Vanagon is
prertty much out of the question at this point?" - She just smiled and said
"Yes, I know".

It's worked so well that she now owns a '78 Bus.
