Edwin came with it from the nice previous owners. I believe it was from Honda, and it is custom with the little slots cut for the air and sensors and stuff.
It hardly weighs anything, so I don't worry about weight at all.
Jane doesn't have it, and driving around all the time in Edwin and Jane both I kind of like the fuzzy carpet Edwin a little better than the plain Jane Jane.
I haven't gone out and bought one for Jane, however, so you can see that I like it A BIT better not a whole lot better.
It reduces glare a bit and it keeps the dash out of the sun so that it doesn't wear out from the sun.
It's a positive, but a minor thing overall for me.
p.s. If my GF tried to steal it and put it in Jane instead of Edwin, I would cry.
