In a month I will have been married for 35 years. Even though we were young when we married, she understood my obsession.
My kids have also grown up in it.
It did take a little explaining when I bought the Z. I already had the 911 turbo and M4. I told her and my daughter that I wanted to buy a Z4 (my daughter has a E85 Z4). My wife said "what are you getting rid of", my daughter said "haha funny". That was classic.
