If it were 200+ miles, it would be great. 100 miles to me just means I'll probably get 75-80. I make frequent trips up to Irvine,CA and it's about a 65 mile trip one way. I know a few charging stations at malls and grocery stores, plus the office I visit has a few charging stations. And even though I can get validated parking, that ChargePoint costs me about $10 to charge every time. $10 for 65 miles is far more than gas would cost.
I know I really cant' go beyond 60MPH most of the way(and there are no real alternative routes due to a Marine base), so if I'm getting about 65 miles now most of the time, and sometimes less if there are no traffic jams along the way, 100 miles just means 75-85 most of the time for me. There really is no point to upgrade, probably for a few more bucks at that, for 75-85 miles. Now if I could get around 175-185 miles(based on some 200 Mile claim), I would definitely be all for it.
But that range anxiety pretty much exists every time i drive this car because it's been towed multiple times and it pretty much lasts about 65 miles half the places I drive. 85 miles would just mean a little less worry, but not really worth it. I'll just wait for one of the other 200 mile cars to come out.
