I (finally) ordered my M3 AWD LR (woot!) But.. I live in a condo (rental), so virtually no chance of getting any kind of charger installed (even 120V). And my work doesn't have a charger. I'm most worried about winter, since that vampire drain sounds a bit dangerous in my situation anyways... On the upside, it looks like they're installing a supercharger within walking distance of my house "this year" Am I crazy...?
