I hate to drag this on, as I've already made my decision and have purchased a ParCar. Please no comments, some people love them, some don't.
I posted a summary on my research here on another thread some weeks ago. This week, I was in Ocala to get service on my car and decided to walk down the street. Went into Carts & Clubs and had a very interesting conversation with the owner, Ted. Anyone thinking about getting a Yamaha with the new 8 - 6 volt batteries should talk to Ted before you do. (352) 351 2278 or better still, visit him on RT 200 just down the street from Toyota. As I said, it was a
very interesting conversation. He will even provide name and phone number to call to back up what he said. Plus, his prices are a little better then locally and he will build it the way you want it.

No need to buy Tier 1 & 2 if you only want Tier 3. Enough said.
