Thanks.
What role does it have? Is it used by a character, or just displayed?

I added some pics:

Yes, the episode number "2.02" was mentioned

Thanks for adding the listing. The episode was "Who Killed the Motor Car Maverick?" season two, episode 2.

I added a page:

Even without a picture, that car is rare enough to be mentioned.
But it would be better if you had a capture of it taken from the series

I wanted to add another suggestion to the VECTOR listings:

"Burke's Law"
Who Killed the Motor Car Maverick?
http://www.imdb.com/title/tt0533912

The episode features the VECTOR Avtech WX3 as a new electric car, the Solar Flare.
The Vector appears in the opening scene and a few scenes into the film.
