I'm 18 years old and I've always wanted an Audi Q5. Currently, I'm working full-time. I earn £28,800 annually and that will be due to go up soon. The car I've had eyes on costs £31,789. The monthly costs will be £632.02. It will be a hire purchase finance type with a contract length of 4 years. I have the deposit ready to go at the time of this post, 20% which is £6,400, and I am contributing more as I won't be buying the car until February. I've checked the insurance and it costs £2,500. With that I will be going halves with my brother as he will be using the car.
At the moment, I live with my brother and work for him. I am currently paying no bills but my phone. My role at work is stable and is unlikely to change any time soon.
Edit: I've asked around and a lot of people are telling me to get a cheaper car as I could crash it or could use the money elsewhere.
Should I buy a second-hand cheap car or go ahead with the deal?
