That would depend how much you value cars. To a non car enthusiastic, spending lots of money on a car seems very stupid as they believe that there are better things to buy. It doesn't matter if you spend all your money on your car, as long as you are happy and enjoy it. Saying that, you'll always be in a better financial position if you hold back now and buy a bomb. Then you can save up and buy something bigger being a house or a better car(gtr). My car now is costing me a sh!t load however I made this sacrifice because I wanted to enjoy a nice car when I'm young and then maybe settle for something more boring once I start a family etc. I did however start off driving 2 bombs before stepping up for something more decent.
I see lots of people blow their money on alcohol/smokes etc, and to me that's a bit silly but it's also understandable because people have different interests and pay for what makes them happy.
