Don't be afraid to buy new if it's a reliable car like Toyota, Honda, or Mazda.

Mazda 3, Corolla, Camry, civic, accord. Personally I'd go for a Mazda 3 for the style haha and the fun of it. But Camry is best bet for just no nonsense.

You're doing awesome for your age, well ahead of your peers.

1. You should invest the amount into your 401k to get the company match. I'd personally only do that and nothing more.

2. Alongside this, invest the full $6,000 into a Roth IRA. Do something simple like VTI or VOO.

3. Dont move out until you can get a 10% down-payment on a home. I know it sucks living at home because you think it might impact dating, but if you have a house at 25-26 your dating life will be amazing compared to renting from 24 and beyond

For a car, take your post tax income/2, and that should be the maximum budget. It can be a new civic, new Mazda 3, Corolla. Or a used luxury car. Just don't buy anything crazy over the limit.
