I buy very few big-ticket items new. Cars? Used, DIY repair for everything except tires, drive them 10-15 years until New England rust kills them. Computers?

I buy very few big-ticket items new. Cars? Used, DIY repair for everything except tires, drive them 10-15 years until New England rust kills them. Computers? Work buys new but I try to skip an upgrade cycle. (I'm on a 2019 MBPro; prior to that was a 2013.) For home, I bought the kids open-box low-end gaming PCs (~$650ea) but for myself am using a perfectly usable Haswell-era Dell I bought on Craigslist for $75 and upgraded with an SSD. Phones? We buy 1-2 year old iPhones and run them usually through a second battery [DIY replaced]. (Kids and I are on the iPhone X (qty 2) and XS still.) For me, it's partly about saving money and diverting that money towards retirement, but it's also a matter of "I don't need or want to go through the shopping and upgrade process every 18-24 months; I have better things to do." I shop well/carefully but infrequently.
