Congrats on your purchase! Very, very nice find! Equipped with a sunroof. And is that leather?? Not used to seeing well equipped 4-doors.

Yes, HUD can be added. How easy it will be depends on your car. If you pop off the plastic top portion of the dash, and dig around a bit under the dash, you may find a bundle of wires/harness taped to the dash somewhere. Most '94 - '96 GPs had them. If you do, you're in luck, because everything will be a simple plug and play. If you don't, it can still be added, but will be a much more time consuming pain in the rear because you will have to cut and splice all the wires for the HUD into the appropriate wires from the gauge cluster. It's been done many, many times, but it's tedious. The same scenario stands for the driver info center (DIC), as well, though you will have to get a '96 specific DIC on account of that being the first year for OBDII, and the '94 - '94 OBD 1.5 DICs are not compatible with it.

Hood lovers can be custom added, of course. In fact, there was a very rare "GT" edition 4-door that came with the louvers from the factory. Too bad I just sold a green set, though I do still have a red set.
