I've been looking at this for sometime, and considering m y options. The 3000$ is for the kit which doesn't include all of the parts, the 4000$ is a fully assemble BugE being sent to you minus the batteries. Batteries aren't included cause of shipping cost, could you imagine the charge of getting those sent over not to mention the hazardous material that it would be considered. I'm considering getting it fr the summer when gas around here will breech 3$ not much for some state but TN doesn't have a high standard of living that can compensate for such a price.
It just came to me about blogging lol. Its like an orgasm a few good shots and the rest is dribbles lol!
