I suspect the biggest win is getting over the mostly mental hurdle of “I deserve a new car because reasons...”, deciding to buy used, and then just not picking absolute maintenance hogs. Most cars are quite reliable now and can easily go 150-200K miles without major drama. 10 Audis owned for 10 years will likely cost more than 20 Toyotas owned for 10 years. Even “over paying” at a place like CarMax (who makes it “easy” to shop for a late model used car) is better than getting fleeced at the new car dealer.

People love buying new cars though... It’d be a lot more amusing if it weren’t so financially harmful. (I confess to buying a new electric LEAF but only because it came with $10K in government money in the trunk. Even with you guys buying 1/3rd of it for us and Nissan financing it at 0% interest, it’s noticeably more expensive than our other cars. Good car though. Has needed wiper blades and washer fluid in 55 months of ownership.)
