I would have to say a TX9 AAR Cuda, 4 speed, with rim blow steering wheel am/fm cassette (PDB standard with AAR Package correct?), PS, and any other options I could think of.
Non E-body would be a 69 GTX black on black power windows, hemi (and air grabber), 4 speed 3.54 dana, power disc brakes, manual steering, wood grain steering wheel, bucket seats with console, am/fm 8track with rear speaker, tinted glass.
