I used to build racecars so I've seen it all when it comes to the "wife says".
I say stand your ground.
I saw a friend lose his dream car. His wife wanted a new Prius and she made him sell his '64 1/2 Mustang
and he got stuck with a 15 year old Honda and she got the new Prius. Next to go was his wood working tools so she could have more room in the garage to store useless ****. Then he had to give up softball to spend more time with the kids when she went back to school. Now he's a miserable housewife and she's gone all the time chasing HER dreams.
It's a 2 way street. You need something too.
