I went through the same thoughts as well and actually read something here that helped me get on with it.
Someone said the warranty is basically an imaginary line drawn in the sand. At some point you'll reach your 3/36k right and then you'll be paying for everything that breaks out of pocket then and from that day forward.. So why let it hold you back from modding the car now and enjoying it NOW the way you truly want it.
With that said I ordered the Procharger.
