up my Z with my new engine just in time for ZCON. And I am pleased. And unlike some of the sheep in this forum, I do my research, ask questions and make up my OWN mind. If I make a mistake with MY choices, it's MY mistake. As with everything in life, it's all about relationships. I have established a good relationship with the folks at Z1. They have made mistakes on my car. But they have always fixed them. If anyone knows of the PERFECT mechanic/service center, please let me know. Until then, if you have not had a personal experience with Z1, why spread rumors.
