I'm also in Indy and drove home my 2014 Rex from Minneapolis about a month ago. I LOVE IT! You can't beat the value on a 2014, IMO. I was mainly shopping Chevy Bolts and Teslas, but I got a really well-appointed 2014 i3 with most options I wanted and a set of winter tires/wheels for $12k. Man, the savings alone over those other two cars is just crazy.
Yes, buying used is a risk. I'm no expert, but it seems there were some common issues with 2014's, but if they've either been fixed or the car has 40k+ miles on it without trouble with the below, you're probably out of the woods:
- Plastic motor mounts and smaller/weaker bolts
- High voltage battery cables
- Rex generic "drivetrain" error (sometimes cheap fuel pump, sometimes expensive total replacement)
There is a way to check what that car says is the maximum battery capacity left (Google "Batt.Kapp.Max"), but there's a lot of disagreement about how accurate that is. I'd still check if I were you, and if that value was under 15 I'd be leery of buying.
Personally, the Rex was a must for me. My commute is typically under 40 miles RT, so even on cold winter mornings when my max battery range is 50 miles, I'd be totally fine. That said, I've already twice had to use the Rex: once when a work meeting was scheduled out in Crawfordsville, about a 70 mile RT for me, and a second time when I had to make the commute to work, then almost immediately drive my daughter to an activity about 15 miles away with no charging available. If you're 99% sure your winter driving will either be limited to 50 miles OR you'll have access to charging at destination every time OR you'll be able to use an ICE vehicle on long driving days, then the BEV is most definitely cheaper and more reliable. That said, I couldn't make those guarantees and the Rex has already been a necessity for me.
Oh, winter tires are a must in the Midwest. If you can find a used car that includes them, it'll save you a ton of money. You can buy a set for around $600, but unless you want to pay a shop to mount them for you every season, you'll also want an extra set of wheels which will cost another $800 minimum. I was really fortunate to find a car that included a set.
