My first EV was a 2013 Fiat 500e. I drove that for two years, loved every moment with it, and then recently made a sweet deal on a lightly used 2017 FFE. I am not sorry I bought the FFE. I am hoping we have many years together.
I was finally leaving the Fiat because of the range and lack of DC fast charging. It is a great car, using some fairly high-quality parts from Bosch and Samsung.
When I first purchased the Fiat, I was also considering a 2012 I-Miev, or a 2014 Smart Fortwo ED. To replace the Fiat, I considered a 2014 RAV EV, a 2016 Spark EV, a 2015 Mercedes B250e, a 2014 BMW I3, a 2017 FFE, a 2019 Hyunda Kona Electric, or a 2019 Kia Niro EV. Notice no (cough) Nissan Leaf (cough).
Yes, that is a big price spread. I shopped for over a year. I drove many, and it was quite a difficult decision at times to pick one car, or see what the future would bring. Though there were several great deals that got passed up, my FFE was an incredible deal.
So I believe your heart is set on the FFE, and it is a good choice, but here are some of my concerns, likes and dislikes of the fore mentioned vehicles. (Not that anybody asked for this.) Note that the prices are for the SFBay Area, where everything is expensive.
Fiat 500e $6000-$8000
Good - So much fun to drive. Cute as hell. A "sleeper" car that can put more performance vehicles to shame. High quality powertrain parts. Active liquid cooling battery thermal management. Very nimble. Extremely reliable. Bright colors.
Ok - Range typically 87 miles for 70% freeway and 30% street driving. 6.6kwh charger.
Bad - No DC fast charging. Dealer network is there, but not that much support. Seats only two normal sized adults. Two kids in the back though. Very little technical information available, in case I want to do my own service.
Mitsubishi I-Miev $5000-$7000
Good - Small but spacious. Ugly cool. Third-party diagnostic support through Canion app and many youtube videos. Very simple design. Not a compliance car.
Ok - Depreciates slower than other Mitsubishis. DC fast charging, but....
Bad - Active air-cooling battery thermal management. 3.3kwh charger. Range 65 miles at best. Built to a low price point.
Smart Fortwo ED $4000-6000
Good - Cheap. Nimble. Cute. Kind of cool color schemes.
OK - Can't think of anything.
Bad - Feels cheap. No DC fast charging. 3.3kwh charger. Battery warranty might require a $5000 payout, or maintaining an $80/month rental fee. Range about 70 miles.
Toyota RAV4 EV $12000-18000
Good - Tesla battery and active liquid cooling battery thermal management. 10kwh charger. Rides and drives like a Rav4. Nice IC and center console displays. Good support from Tesla. Plenty of space. Range typically 130 miles.
OK - Can be modified to DC fast charging, but $3000 plus labor.
Bad - Tesla powertrain. Other sore spots, heater, gateway, DCDC converter, touchscreen. Requires a Toyota Platinum Warranty to guarrantee no exhorbitant repairs.
Chevy Spark EV $8000-11000
Good - Sportier than the Fiat 500e. 400 FtLb torque. Nice IC and center console displays. The best active liquid cooling battery thermal management. DC fast charging. Chevy very supportive of the vehicle. Most efficient EV. Range better than 75 miles, 96 fwy miles possible. Bright colors.
OK - Previously, the best new ev price to performance/features value.
Bad - Can feel a little cheap. 3.3kwh charger.
Mercedes B250e $16000-21000
Good - Very luxurious for the size of car. Tesla battery and active liquid cooling battery thermal management. 10 kwh charger. Nice color selection. Nice IC and center console displays. Variable regen. Range about 110 miles.
OK - Can be modified to DC fast charging, but $3000 plus labor.
Bad - Tesla powertrain, though not as bad as the RAV4 EV. Mercedes reliability. Dealers run and hide from the car. Ridiculous warranty stipulation that dessicant bag had to be replaced every year for battery warranty to be honored. In other words, most B250es have no battery warranty.
BMW i3 $16000-18000
Good - With Rex, range is effectively infinite, but requires hack to be usable. DC fast charging. OK IC and nice center console displays. Phenomenal design, construction, and interior. Active vapor cooling battery thermal management. Nice colors and quirky look.
OK - BMW reliablility. Rex made by Kymco, while a reputable company, it really should be made by BMW. Battery only range about 85 miles. 6.6 kwh charger.
Bad - 2 gallon gas tank. Destructive battery heating methodology.
2017 FFE $15000

-$21000
Good - An electric Focus Titanium. DC fast charging. 121 miles range. Nice IC and center console displays. Active liquid cooling battery thermal management. Nice color selection. Beige interior standard.(yes!) Quieter than the Fiat 500e.

Hyundai Kona Electric $36500 (before govt rebates)
Good - 60KWH battery. 260 mile range. Cool IC and center console displays. 100 kwh DC fast charging. Contemporary interior. Multimodes. Nice color selection.
