I bought my 325 from Peter Pan BMW before I moved up here to Portland, so I don't know how the sales department is, but Kuni's service department has been amazingly good.
The window regulator broke with the window in the down position one drizling Portland afternoon and Kuni had me in and out the same day for the repair. The sales guys let me take a brand new (at the time) 5 series out for an hour long test drive while I waited.
Kuni also had no problem with the full BMW warranty coverage on brakes and clutches. Even though they know I regularly tracked the car and drove the piss out of it, they never once had a problem paying for 2 sets of rotors/pads in the front and one set in the rear, plus a clutch.
I have nothing but praise for Kuni...
