... that Tesla... dreamy... I could buy a cheap electric ...
... or build your own!? When you have a moment, have a look at http://www.robertqriley.com
Pull up the web page for the plan set for his URBA ELECTRIC or the other one he calls URBA CAR. There's also a three wheeler (a modified motorcycle (or if you wish, an all electric version) all of which might be worth looking at.
On this end, I bought the plans for both the Urba Electric and the Urba before finding out about the little Honda Insight.
The true cost(s) to (properly) build these Urba vehicles which Riley offers plans for, is about ten thousand dollars, when you take into account material AND labor. The new Insight cost me just slightly over seventeen thousand, so I opted for the Insight which came with a few "bells, whistles and chrome" I wouldn't have otherwise had were I to build one or both of the cars I'd bought plans for.
You might note, when the plans for the Urba and the Urba Electric (both are different cars by the way) the battery technology and the small engine technology in those days was no where near as advanced as it is at present and will shortly be; NiCAD cells and the more advanced NiMHD cells and like were just lab curiosities in those days. But make no mistake, the plans for the fiberglass shells and the steel tube frames are just as valild today as they were when first drawn up.
If you honestly want an all electric vehicle for highway use, do have a good look at the Tesla, then consider what you might be able to do with that same power supply system were you to build your own vehicle shell using one of those Riley plans or plans like it - of which there have been and continue to be many.
Hope this helps some :-)
