I commute 120 miles one way about 6-8 days monthly. Interstate miles. The balance of my month, I commute 45-50 miles one way. I live in Louisiana, were the winters are mild. On the Long commute, the is a convenient supercharger near my destination. On the shorter commute days, I will have to rely on the supercharger a mile or two from my home and then make the round trip without recharging. I have narrowed my search to a pre owned 2014 85KW. 19 inch tires. No pano. Coil springs. Listing my intended options in case they might have bearing on your answers. My question (or concern) : Am I making a sound decision based purely on my travel distance and charger locales? Should the mild winters of 30-50 degree average greatly affect my ability to commute? How much time can I expect to extend my current commute time when considering supercharging ? Speed limit is 75, but what do you recommend as an average speed on the highway for efficiency? Thanks!
