Hi,
I owned the 2000 MT Insight new, though it just died (see "would you buy another" post for the story), and I got a 2006 MT also silver. The Dodge Caravan was a factory conversion with GE, that made 56 (at $100K per) for eastern utilities, half with Nicad's, the rest with Lead batteries. I found it on Ebay, but it turned out to be a restoration project, needing lots of professional hours, and an expert EE to troubleshoot and rebuild the CB and now reprogram a logic chip. I'm told it's close to running well soon.
