Regarding cars, I would call me not cheap, but frugal. In my 40+ years of driving, I just owned 7 cars. All of them were bought used and were at least four years old when I purchased them. And we put a lot of miles on them. My first car in the US (after I moved here from Germany) was an Oldsmobile Custom Cruiser, and we took it for trips from Rochester to the West Coast, to Florida, to Louisiana, and to Newfoundland. It died with 270,000 miles on the odometer.
Currently, I drive a 2010 Odyssey and my wife has a 2013 Honda CRV. In our upper middle class neighborhood, these are the oldest cars you will see around.
