I am 37 years old male, married with kids (5,3,1). My parents are from the Indian subcontinent but I have lived in the US for most of my life. I have always been very close with my mom, ever after marriage I call her every day and visit her at least twice a month.
She is a great mom but her personality is she has always been a control freak and very frugal. I recently told her that I am planning to buy a new car since my current one is 8 years old and has 100k miles on it. But she said it would be a waste of money and that I should save for my family and my kids. She said since my car is still running fine I should be patient with it.
I know in the culture she is from, parents have much more control over their children. I don't think I can ever I convince her that things are different here.
Should I buy the car against her wishes and risk damaging my relationship with her since she was adamant on her position, or should I keep trying to get her blessings or should just listen to her and forget the car?
UPDATE
Thanks to everyone who answered and commented. Yes, the question is not really about should I buy the car. Although I can buy it without taking a loan, that money might be better spent saving for a home or my kids college or retirement or a rainy day (as people here have advised). It is somewhat of an "impulse buy" because I like picturing myself in that new car. My wife already has a minivan which is relatively new so the kids are fine.
The question is really about cultural clash in relationships. As people here have said, I am in "independent human being" and I don't need to listen to my mother about my financial decisions. But that is not how she sees it, she thinks because she is my mother she still has the right to tell me what to do (including how I spend my money). So the question is how can I live an independent life and still be on good terms with her when she has such a way of thinking (which I think comes partly from her personality as a strong mom and control freak, and partly from the part of the world she comes from).
