Well, in Western eyes, he risks attracting laughter. Only the new rich show off their money. If you take the example of the Peugeot family, everybody drives a mid-range car from the factory. Yes, it will have the most powerful engine possible and all the other options inside, but on the outside, it looks like a very middle-class, average car.
One friend in Paris was complaining one day. I forget what make of car it was... some super Porscheomaseratti 747GTX or whatnot. Well, he was stuck at a red light in the Latin Quarter one afternoon and some kid, who was crossing the street, pulled a key out of his pocket, and left a long scratch in the hood as walked past it. The cost of repainting over the scratch amounted to over four months of salary at minimum legal wage in France at the time.
Clearly, the kid has never seen somebody work his back off for 12 hours a day on a salary of 10 yuan per day.
