I'm a Millennial I think its more based on where you live, a lot of my friends that are my age who live in Chicago don't buy cars because parking is a big issue and mass transit here is fairly decent.
This is very true, I think. I'm in SW Missouri, many miles from any city of any size (KC, Tulsa, etc.). There is no public transportation, no bus lines going through here, no passenger trains, no Amtrak, no Uber, no ride sharing, no choice. If I lived in a metropolitan area, I'd take public transit to work (before I retired) but there was none, so my car sat outside in the parking lot 8 hours a day, five days a week, subject to door dents, hail, rain, ice and snow. Commute was 50 miles every day round trip. No choice except to sell the house and move to another one and hope the job didn't change. I'm 200 miles to the Tulsa airport which we use most of the time and 200 miles to Kansas City airport. I live in my car, even after retirement. But I'm not a millennial either, I'm an old car nut who never grew up and who learned to drive with the best and still love driving what I can afford. Like what you drive and drive what you like.
