Not quite 23, I'm 25 and own 2 vehicles. At 23, I had a Charger and a 300 and got the same remarks but having the SRT-8 and the 2SS bought brand new people think i'm crazy.
I look at it like this, most of the guys complain and are all curious either drink, smoke, dip(I don't do either of those things believe it or not) or find themselves spending money on strip clubs. People choose to spend there $ in different ways if they actually thought about it, they could probably afford the same things I do.
