Are you suggesting to ignore friends/family? What if they offer you a car ride, and start bragging about their car? Not just once, but over and over. And they have a Bentley, and you have a second hand Toyota? How are serious mind tricks not necessary here to keep your sanity?
What's the problem? Tell the truth that it is indeed a nice car.
If you have sanity issues because you ain't driving the nicest car in town... Maybe that's the core issue? Why do you place so much importance on having the nicest car? Vast majority of people do not give a damn what others drive/wear/whatever.
And Bugatti would make Bentley a not-so-nice car. But once you go off tarmac for your forest cabin, both cars will suck. You may enjoy your 2nd hand toyota, especially if it’s rav4, much more…
All in all the only way to win this game is to not play.
