Congrats!
Best colour, too.
I drove my 2000 for much of the time with the hybrid functions disabled. I wouldn't necessarily spring for a replacement pack before trying the trickle charger, or without IMA at all.
Also: first mods should be the engine kill switch (yes, it has autostop, but it doesn't do it nearly as early/often as possible) and the clutch switch (which enables you to control when you get assist).
Fun car!
I was just saying to Tim the other day I was having a hard time deciding whether I had more fun driving the Insight or the Prius. Both are awesome geek's cars.
