man i only told you what i heard from the dealers here in karachi @sharea-e-faisal. the UG only was the last few cars which were given the leather interior / special seat covers, silver interior (the black inner panels were silver as in the cultus thingy explained above), and thats it. that even for a 30k extra! like the timewhen they changed the city 2004 shape to 2005, they offered UG packages.
personally i have only seen 1 here in karachi owned by a friend and he has it in black color EXiS version manual transmission with the upper things!
that is it...i have no responsibility and do not own the UG version (Y)
peace!
