Planning 2003 Dodge Neon Conversion..Need a good starting point!

[ATony]

I am not a very good mechanic, but do have a background in mechanical design. I am hoping to get about 100miles on a charge maybe less. I wish to be able to go at least 60mph top speed but not more then 80mph. Money has not been allotted for this project will plan first. I have considered a design that i think might work, but i know nothing about electrical environments.

Edit: I would also like to incorporate solar power into the car weather or not it is a big help.
