I completed the first year of ownership with my 2021 XC 60. It has been a pleasure to drive. I took for its first service and had Polestar added to it. You really feel the difference.
I had it added to my C 70, and I really like it. There are times when driving that you really need that extra torque.
One thing that was and maybe still a concern, was the front rotors had to be replaced. I could tell after about six months in that they were starting to vibrate. It got worse and worse.
The XC 60 has 3700 miles on it, so hopefully just a set of rotors, not something that will be a on going thing.
