Ive got a Manual VT SS. But previously owned an Auto VU S ute. And my gf currently owns a VU SS thats an auto as well. Manuals ARE generally harder to come by. Especially in the V6's.
Edit: People who do own them and want to sell them know this so put a price on it to reflect that. Have a look at the ad's. 90% of them will have 'Rare' or 'Hard to find' Manual written in them
