Good luck man. I feel really sorry for you for making this decision. A car doesn't gain value and is not an investment, only a money sinker. Using already 50% of your income on a vehicle is a poor choice. I don't believe you even factored in gas,maintenance, daily life bills, maybe wanting to take a special someone out on a date.
Do you even have an "oh s***" fund for when something big breaks on the vehicle or you lose your job? I was happy I had gotten a 99 Nissan sentra as my first car. Couldn't imagine my life now if I had the wrx back then.
