Probably our car. It's a great car, I spent weeks researching the perfect car for us. I love it and I'm grateful every time I drive it, but we bought it on credit and it's way out of our price range to buy. It'll take us about 6 years total to pay it off.
I still understand my decision at the time, but it was driven by a specific chain of events that made it make sense, and in principle I'm against buying a car on credit, just buy an older reliable car you can afford.
I understand and agree with your attitude to buying a car on credit. Two semi-objective justifications I can see are safety and quality-of-life.
Newer and better cars are safer, and you might not have even a minor collision throughout the whole lifetime of the car, but the (hopefully never) day a crash happens you'll be forever grateful to yourself you bought this car. And if you have some "smart" assistants on-board those actually can make you not end up in the accident.
From my experience I have realized that (within reasonable bounds) if spending more on something results in substantiality higher quality-of-life then it's a money well spent. Because you end up being happier, calmer and actually more productive if you don't have to waste your energy on inconvenient things.
Some of the considerations we took when choosing the car, I totally agree. I don't regret the decision, the monthly payments are not a huge burden on us, fortunately, but it was still not the best financial move.
