The cost of the car to convert to electric is the least expensive item when building an EV. Most people don't understand this, because it is completely opposite for a gas car, where the car is the major expense.
You can save $1k-$3k on the car, and then spend $10-30k on the rest.
The major expense in an EV is the BATTERY.
You should plan/optimize everything else around it.
If you are using a massive pack of lead batteries a Cherokee might work OK because it can handle 1500lbs of batteries.
That said, you should also convert what you want to KEEP, because you will never be able to sell it for what it cost to build.
I have a '89 Cherokee for towing my boat, and I love it, the I6 lasts forever, 4WD/AT is great, but it has about the worst aerodynamics of any car except for a Hummer.
Thanks guys. Yeah, I know it's not the most suitable, but a very practicle vehicle for my needs and I happen to have one in my driveway with a blown ICE. I guess I could just keep loading batteries in the thing!
