Asking $20,000 Azure Blue - auto with 48K miles. Does have custom exhaust. It has the "DC" 2005 update drivers side head. If you are shopping for a 2003-2004 Mach 1 or Cobra you need to fully understand the exhaust valve guide issue. Ford did make updates during production to try and fix the problem, however the cooling issue by most opinions was only resolved in the "DC" casting change not released until 2005.
