After reading over his reviews & being referred to him by another mechanic; I decided to give him a try even though I was hesitant. So I took my 2004 325ci to him & I have to say, I was pleased!! He does come off "hard" at first but that to me, is just someone who knows what they're talking about. It does get annoying at times when u have to take ur car back for something else but if you're logical; you know that fixing a car is like going to a doctor. It's process of elimination. And with Koz, his process of elimination, seems to me, to be, to start with the most likely issue and least expensive one. He seems like a very honest man and I will say his prices are reasonable. No one likes to fork out a few hundred for work but if it's needed, you gotta do it. And it's much cheaper than going to the dealer. I purposely waited a few wks to post this just to ensure that i didn't have the same issues and I don't. I absolutely plan on going back and I'll even be taking my 1989 325ci to him to start work on that one. He's got my vote!!!
