It only has 14 K miles on it. The roush stage 3 would come with roush bling / roush suspension / roush blower. The PD blower gives you the instant Tq hit, right from idle....instant boost. You don't get the instant tq with a turbo.
The Roush suspension package would come with roush front / rear lowering springs..and roush monotube front struts (which are 1/2" shorter than oem, the roush front springs are also 1/2" shorter than oem.... making up the total 1" front drop). Roush 37mm front sway bar..and 27mm rear sway bar.... + rear monotube shocks. Roush uca mount assy.
That would have been a VERY expensive car when new.
