How Much Should I Sell a 88 GT with 19k Miles?

[Wisc5Ltr]

I know that KBB pricing sucks.. but what should I sell it for?

Its a 88 GT hatchback - never seen snow and very limited rain..
Grey Metallic upper, silver lower, red stripe - Red cloth interior
19000 Miles
AOD
Add On: AT flowmasters, 3.73 gears, FMS Pulleys, KN, Weld Wheels Draglites (15x7 and 15x8.5), BFG Radials, Pioneer CD Player..

Not Installed: Twisted Wedge Heads (Ported and Polished - .600 290int - 197ex), GT 40 Intake (Ported and Polished), Mac LT headers - all three are gasket/port matched, BM shift kit, black magic electric fan, 89 computer/mass air harness with wiring, Gauge Pod with Monster Tach, and E303 cam.

Would I be better selling the parts out right and the car seprately? or package it together..

thanks!
