Without playing games like this, I tend to rely on data more than stuff on chatboards. Consumer Reports, which is still the best source of data in North America (although ultimately flawed) , rates the SPA XC60 as much worse than average. However, the category of suspension and steering is rated as "average". I don't think the T8 or T6 is going to have problems under the car. I again think that the real issue will be failure of plastic parts, wires, and computers. As an example, my former BMW developed a crack in the gas tank (which is now plastic). I complained to my local repair guy with me and he said, "Come out back...". Behind his shop, he had a pile of failed gas tanks. He said it was happening more and more, because plastic just doesn't like constant heat, expanding, and contracting. In the T8, I'm less worried about the ERAD than I am about all the plastic bits and the electronic complexity. Its just not a vehicle that I'd want to own long-term. As for the T6, two forms of FI and the same preponderance of plastic gizmos. In all honest, if I planned on owning my car past 100,000 miles (which I rarely do), I would have gone with the T5. I would not bet on the reliability of the T6 OR T8 though.
