I'd been planning to get the HPWC, but a consultation with an electrician confirmed that I don't have the juice to do a 100A install without serious panel upgrades. Even then, I was thinking I'd get it, for three reasons: 1. Convenience of having the HPWC mounted to the wall, v. having to drag the cable out of the trunk every night; 2. The possibility of being able to charge faster when on the road, if I find an HPWC; and 3. Resale. But then I spoke with the consultant at the dealer, who said that even the HPWCs at the dealers don't generally charge at the full 80A. So then I thought maybe I should skip the HPWC (and twin chargers) and just get the fancy stereo, which costs way more than it should but which I'd actually enjoy (particularly the XM bit). Thoughts? I could theoretically get both, but I have to draw the line somewhere--and for me, 95K is the limit I've imposed to maintain sanity. If it's relevant, I don't have a garage and will be charging outside, which is one of the reasons I can see the appeal of not having to wrestle the (possibly wet, snowy, muddy) cable back into the car every morning.
