I just want to make a comment here ...
What is/was available in any given year is dependent on which country you're in.
Also, as far as I know, the entire 06 and later Grand Vitara range IS 4WD - Suzuki does not offer a RWD or 2WD only version - you have a choice of single mode 4WD (AWD, no low range, no lockable center diff) or four mode 4WD (4H, 4HLc, N, 4LLc) - rumor has it that this will change for the 2012 model year.
I have driven an 07 2.0 four cylinder, auto transmisson with four mode 4WD - so they do exist.
