To convert a car to electric, you will find that you don't need many of the thing at the gas car did, for instance the gas tank, radiator, and motor.
the electric motor is much smaller the a gas one.
many people are building a battery pack to go where the gas tank was along with using the extra space in the engine compartment.
this is a link to what some others have done.

i would recommend using a midsize or larger car, or truck. the reason is tha toyu have more room for batteries, and you can also install a small gas powered generator to recharge the batteries as needed. i recommend something like a mid 80's grand marquis or crown vic. when you get ready to do the conversion, check out as they have plans for doing this very conversion.

if you dont want a crown vic, get something like a ford ranger or chevy s10 pickup. these will also have the room you need for batteries and generator, and they came with manual transmissions.

As a general rule of thumb, lighter cars work better when converting to electric.

I'd say a '97 Geo Metro. I found a page where someone converted theirs to an EV.

It has a 50 mile range, a 70 mph top speed, and manual transmission.

I'd need your (limited) price range and zip code to get an accurate price of the car, or you could look it up yourself.

Good luck.

If I were you, I'd use a Toyota MR2 spyder. You could save some weight if you swapped the somewhat high-performance tires for cheaper, thinner ones. Also, the engine is mid-rear, so the car will be well balanced when you replace that engine with your electric motor. If you needed extra space for batteries, you can remove the spare tire and use the small trunk in the front of the car.
