Luckily my wife is very supportive and knows what I have spent, she once told me to get rid of a horrible rear wing I put on and buy a nice curved one, I pointed out how much it was and she just said “so, buy it the other looks horrible” it was the Reverie one I bought in the end!
I was tongue in cheek. I have a supportive wife as well.
She understands that I work hard and is happy to support my car hobbies. Family / House / Cars in that order have served me well. I do get the occasional eye roll , but hey ho!
