I feel very guilty purchasing a nice car and I don’t know why.

I grew up poor. I’ve worked two jobs for long periods of time. I graduated college in December and I wanted to treat myself. I’ve driven shit boxes my whole life. I’m completely debt free. I ended up buying a 2021 Mazda 3 for $15000. I wrote a check for the car. Since I had cash I was able to negotiate for 15k out the door. I love the car, it drives great. I never had a car with a backup camera or bright led lights.
