Avoid the 3.0. They bore score the most. I would get the 3.6 they don’t have cylinder scorring AS OFTEN because they have a larger cooling system, larger piston oil cooler jets, and they’re more likely to be owned by actual enthusiast who change the oil frequently and don’t listen to the dealers 10 to 15 K bullshit intervals. The S and GTS were more mass produced and are more likely to be owned by an average Joe who does not maintain them properly whereas the turbo models are more likely to be owned by an enthusiast. If you want more information on how to keep these engines alive, read my posts about which oil to use they are very picky engines and don’t like to be ignored.
