I get where he is coming from. I used to change my cars every two to three years. In the main it was simply a boredom / familiarity factor coupled with a desire to get back into something a little newer or up to date or higher spec. I seem to be doing the opposite of most of us when we reach our mid forties, instead of the ‘crisis’ I am also much more aware of how much money I was spending (no doubt the car dealers did well out of me) and now I’m spending it on other things, such as my new toy (a stand up paddle board) or simply paying off the mortgage. It’s nice to be free of finance too. I’ll always love my cars and I am guilty of browsing the classifieds from time to time. My 2014 5 series does everything so perfectly and effortlessly; I have a roof box, bike racks and carry my paddle board on it. I manage with two kids (a 5 and 7 year old) and don’t need anything bigger, in fact I could manage with smaller. Keeping a car this long means I don’t have to care about depreciation either; I accept it will be worthless at replacement time and so I feel less pressured. I have no desire to go to SUV such as an X5 as I cannot justify the bills vs value I get back from it. It is so personal though and being that I have been guilty of doing both, I totally get it and there is no right or wrong way. It’s up to your priorities . I do also agree the baby stage with all the baggage and paraphernalia is very short lived. I’d suggest stick.
