Congrats on the new car!
All my warranty work has been done at Kuni, but that's mostly due to its proximity to my house and that it's easier to get a loaner at Kuni. Portland had a good deal of turnover lately due to the Lithia acquisition, and it's harder to get into due to parking limits.
As far as mods, I would PM mineo77.
