Purchased 8/7/2018. 30th birthday present to myself. Was looking all over for a GT with all intentions of swapping the 2 valve out for the 4. Then I happen to come across this car that had it already done, and figured it would save me so much time. Mach 1 was my dream car. Now I can customize my own pseudo Mach 1. Car came with BBK Longtube headers and X Pipe. No cats or muffler and sounds amazing. Since this car performs very well im concentrating on the visuals of the car. I will post updayes as they happen.
