I've bought 5 BMWs from Kuni over the past 5 years. I just bought a 330i from them yesterday.
They've always been great to me. They have always done correctly service my cars there and I've never had any problems. Their new facility is great, the only issue seems to be that on weekends the salespeople are very busy and it can sometimes be a wait.
If you do go to Kuni, see Wally and tell him that Brian C. sent you.
