As much as I enjoy my new Zenn electric vehicle, there is a down side. After buying my Zenn, I was very disappointed to discover that Zenn corporate rarely answers email inquiries. I have telephoned Zenn many times to ask a question, and am told that the person who might know the answer is "in a meeting", or "out of the office". I've also tried to leave voice mail, but they don't call back. I've even waited for over 2 weeks for a call back that never came, and my last 2 emails (one sent on 1/30/08 and another on 2/3/08) have not been answered. I complained about this to Zenn's vice president of marketing, but it didn't help. So a word of caution: If any of you are planning on buying a Zenn, you will get a nice neighborhood electric vehicle - but after the buy YOU WILL BE ON YOUR OWN. The paths of communication at Zenn just do not exist.
