Right now we have three cars. (1) Nissan Leaf 2015 S. (2) Hyundai Sonata 2011 (3) Lexus IS300 2001. We almost sold the Lexus when we bought the Leaf, but decided to drop all but liability on it and keep it for the random day when both my wife and I need long range cars. Honestly, there's been maybe 2 of those in the last year, so I'm re-thinking keeping it.
My goal in to have in 2-3 years time a new Volt and a Tesla Model 3. Here's my plan. Track the resale and capacity bar on the Leaf. When it looks like it may drop the first bar soon, I'll sell it. This may get me to a Tesla model 3 but not likely, if it doesn't get me there, I'll go buy a Volt and sell the Leaf and the Lexus. With tax credits this should put me out about $10K or so. Then when the Tesla model 3 comes around, I'll buy that as well and sell the Hyundai.
The kicker will be the tax credits. I may be persuaded to buy the Volt sooner if it looks like Chevy is going to lose the $7500 federal credit because they are getting close to 200K cars sold, I'll also be keeping a close eye on the $1500 CA state rebate and whether its going away. I also may be swayed if the Tesla Model 3 is taking way too long, but we'll know more about that car in March or April, and I plan to put my deposit down ASAP. If the Tesla is taking way too long maybe I'll be convinced with a Bolt or a Leaf Gen 2. I'll likely stay aware from the 2016 30kwh Leaf because I think it will be quickly outdone by the Bolt or the Leaf Gen2. The only way I would consider a Leaf 30kwh would be if they start trying to dump them like they are the 2015 models right now. If I can pick up a 30kwh 2016 for $5K NMAC discount plus $5K dealer discount, plus 7.5K federal credit, plus 2.5K state credit. I'll go buy one next year and sell my 2015, but I don't think they will drop that model so low in price. At least not until the new Gen2 is just around the corner.
Oh, I don't think I answered the question. Yeah 150-200 miles of range would change my habits. I wouldn't drive like a grandma, I'd use my heater more often in the winter, and I'd probably rack up about 3K miles more per year on the car.
