Heynow999, you didn't mention what your primary use for the iMiEV will be, nor whether you have a second vehicle for longer trips. In your neck of the woods, reduced range in winter may also be a consideration.
For us, the iMiEV fits our intermediate-range needs that accounts for most of our daily driving, with a very-efficient hybrid (Gen1 Insight) for longer trips. My other EVs fill the short-range drive needs, although a bicycle is a helluva-lot healthier if time allows. With solar, our "fuel" cost is essentially zero, as the cost/amortization of the solar panels comes from a different pocket.
Just as there will be a better computer, a better phone, a better TV, etc., there will (hopefully) be better and longer-range EVs in the not-too-distant future. High price for a not-fully-refined product is the penalty of being an early adopter, although I'm happy to see that both the Leaf and the iMiEV are very nice already. The iMiEV is available NOW, and we're happily putting on the miles (1500mi in six weeks) while everyone (except my Leaf buddies) around us grouses over the $4.50/gallon gas prices. Besides, it's one less polluting ICE car on the road. Once the manufacturers get the price of batteries down, EVs may well become cheaper than ICEs because they're simpler.
What drove me into buying the iMiEV now and not waiting any longer -
1. I'm getting old and tired of chasing that carrot that's been dangling in front of me for years. A bird in the hand is worth two in the bush...
2. My wife and I both like small cars. The Leaf I consider a large vehicle, as is the Tesla S and Coda. Both Honda (FitEV) and Toyota (Scion iQEV) had announced they would only be leasing the few they produce for the California market, and a bicycle doesn't even fit in the back of the iQ nor SmartED nor Wheego nor Think nor... if it weren't for the inside-bicycle storage requirement, we could probably broaden our horizon and maybe consider one of those (if we could get one). In the back of my mind was also the fear that the iMiEV might grow in size even more than it has already (witness the now-bloated Fit).
3. Unlike most people, I've never considered depreciation for anything I've ever purchased (um, the 1967 Saab was one of the very few vehicles I purchased new in my life (for around $2K) and is still running and is worth... who cares?), as I always bought expecting to keep forever. If you expect to turn over your iMiEV within five years then, yes, I suspect that will be a significant depreciation hit - but which you could probably rationalize using fuel and maintenance cost savings (do the math).. I personally never understood the math of leasing unless you were a business, and I recall being furious with GM over the EV-1 when it first came out and I couldn't buy it.
4. At this point in my life I have too many varied interests that preclude me from undertaking a conversion (I had been saving a few lightweight aerodynamic Saab Sonetts for years hoping to convert them with a good ac drivetrain and Lithiums).
If you want to save money, then simply keep driving your old clunker... then, when you get old and retired and have saved up the money you didn't spend on new cars throughout your life (do the math) then you can buy the latest whiz-bang relatively painlessly. My wife's '83 Toyota Corolla wagon with only 300Kmiles was her ultra-reliable intermediate-range daily-driver until I got her the iMiEV. Apologies for the philosophizing, but I endured a lifetime of derision at work for driving old (and small) clunkers. :roll:
In the meantime, we absolutely love our iMiEV and haven't found any significant drawbacks to it, recognizing its range constraint which we understood fully before we bought.
