I drive a nice truck because I can. You can drive whatever you want. If you think people drive nice vehicles because of their egos.... I'd say your just jealous. Some folks just like nice things. I pull trailers from time to time and don't care to have a bunch of vehicles. My wife drives a SUV. My brother on the other hand has several vehicles. Two corvettes (2006 C6 and 2018 C7), a 1941 Willis with blown 502 (show car), a ZL1-1LE Hennessee 850 Camaro, and a 2015 Denali 2500. He has ordered a new C8 Vette and is about to order a new 2023 Denali.
Different strokes for different folks.
