I also get a ton of hate. I'm 21 years old, and I look even younger. Everyday I get comments from young people telling me how this isn't my car and that "daddy must have bought it for me" and I've had older people make comments as well about how I must be a brat. Little do they know, I work 365 days a year and own two businesses. I think I deserve to drive a brand new M3 after a 100 hour work week..
There will always be haters. Just gotta brush it off and be careful where you park. And get a beater car
