I, too, converted a fiero -
Dave Brandt's 1986 Pontiac Fiero. It cruised on the flat at about 1 amp for each MPH (e.g. 50A at 50 MPH) with a 228V system.
Parts are readily available. Many specialty stores and aftermarket stores (like
Fierostore.com: The Fiero Store) offer stuff for the fiero. Everything from replacements for the little plastic rivets to body kits.
I agree they are built solid, too. Fit and finish isn't always too great, though.
And the handling - you can take a 90 degree corner at 40-50 MPH without much extra effort or any extra suspension parts.
The bad - hard to find anyone to work on them (for alignments, paint and body work, etc.).
I am currently parting mine out - the batteries and controller are gone. However, everything else is still there, installed, and is a great starter if you are building an EV. Yes, it's for sale. Savannah, GA area. Contact me if interested. ev_dave13 at yahoo dot com.
