One of my best friends, who does better dating wise than anyone I know, drove a 98 Volvo. He was making well over 150k, but had so much quiet confidence he had no need to project anything.
I make a similar amount, still wear clothes from Old Navy and when I do own a car it's the cheapest newish one I can find.
Both me and my friend are essentially social media / online dating free. If your obsessed with trying to impress people you'll only attract those seeking to take advantage of you. The insecurity of needing to be someone makes you an easy target.
