I know I will hear you spent x amount of dollars on the car so don't cheap out, trust me if you can dump thousands into a z trust me I'm happy for you but a lot of us are on a budget but we really love z cars.
That said I will not cheap out on stuff like tires, oil, gas and such.
So let's begin with the car, I wanted a new Nismo, lol, came to my senses and desided on a used sport model with a 20k budget, looked for almost a year and found a 2014 370z sport in black cherry, 7,800 miles, guy got a dwi his bad luck was my good luck, 20k done deal
