It's not $5000 less, it's $7500 less (plus tax).
And *myself*, personally, I don't have the need for an extra 40-60 miles range. In fact, the Ioniq EV (125 miles) is probably all I need - but the extra 30-40 miles of cushion would be nice. I'll use the BEV for 90% of my driving, and my 'ICE' (currently a pure ICE, PZEV, but replacement vehicle will be a fuel-efficient and low polluting PHEV) to be used for trips over 150 miles. My Spark works great for us (family, so we get to fight over who has the privilege of driving the Spark each day). Enough miles for most daily drives - R/T to San Francisco is about 100 miles, so a DCFC stop is mandatory and it bothers my wife, so we generally take the ICE for trips to SF or anywhere in the 'north bay'. Literally, we've only put about 3000 miles a year on the ICE since we got the Spark EV. And that is mostly a few number of long trips (Ventura, Reno, Sacramento from SF Bay Area). We've changed our habits so that we each plan our day around when the EV is available : work commute (often carpooling so wife keeps the car during the day), visiting friends, shopping, etc. is dependent on when the car is available. I was surprised when I realized how much we had changed our routine to drive electric.
It will depend on prices when I 'return' my Spark EV lease, but I'll either dicker and buy the Spark, or I'll pay $5K-6K for a used LEAF-1. And then get a PHEV with 30+ miles electric range, so that 98% of our driving is electric, but we have the option of driving 500 miles at a moment's notice. And a REAL hybrid, fuel- and pollution- efficient, not an i3 with a low-efficiency, polluting "range extender".
