I have a Ghia X, and mine states it on the log book and when i put my reg onto any car insurance site, so try their to confirm it. As mine is a 2.3 petrol mk1 i defo dont have the rear aircon unit only the heater matrix under n/s rear seat. I have same extras as you but also have heated front seats, sunroof, rear parking sensors with LED display. i also have CD changer in the back and the chrome trim round number plate but you may have that as i thought the last two were an ghia x standard addon.
