A 2003 350Z would have absolutely waxed the floor against a 2003 Mustang GT.
287hp, 6spd, vlsd, IRS, 3,300lbs, modern interior and great brakes for about $27k.
Mustang? 260hp, 1979 Ford LTD suspension with a POS 5spd for around $25k.
People spent way to much time crying about the Z's weight and heavy handling when it infact would smash the S2k and RX8 on tracks because of the grip and torque.
They were both low 14 second cars driven by an average person. I never saw better than a 13.9 bone stock from either.
