purchased used and this does not include
the cost of my time.
Additional FeaturesDid I mention it is a convertible!!!
Initial comments: When I drove it for the
first time, I
could not stop smiling and laughing. The EV
grin that
people talk about is really understated.
Especially if you
throw in the mad scientist laugh.
Mwhaaahaaaahaaa! (Corny,
but fun)

After a year: It is still fun to drive the
car. I have been driving it to work for
quite some time now. The only problem that
I have had so far was needing to replace the
master cylinder for the brakes. It's funny
that this has nothing
to do with it being an EV.
