"You can actually work on them yourself, without having to fight some 
automaker's proprietary security stuff."  That said; however, on older 
conversions and on most conversions the conversion documentation is very weak 
and documentation on the individual components is limited or non-exist.  Many 
companies that made battery chargers, motor controllers, meter, and other 
electronic devices had limited documentation or proprietary documentation and 
never a schematic or software source code.  I would rather hack a production EV 
product than reverse engineer or troubleshoot a product from a company that was 
out of business.  A good example is the original EV1 hardware.  Try to work on 
that stuff.  Its value is nil.

Yes, but they have an upside:

You can actually work on them yourself, without having to fight some
automaker's proprietary security stuff.

If the motor or controller craps out, you can replace it (or them) with
whatever new unit(s) you want.  Same with the DC:DC, brake vacuum pump, and
so on.  Same with the battery. You can upgrade or downgrade any component at
will.  You can get parts from any source, not just the dealer.  You won't
have the car rejecting some junkyard or generic part you put in because it
isn't "registered" with the body computer, or whatever.

There seems to be a large and growing "hacking" (in a good way) community
devoted to some production EVs, but even those are still much more locked
down and opaque than any conversion.
