So i got some new winter mats, they are a darker grey, and my interior carpet seems more tan then grey now. It does have some coffee stains (rying to remove in spring) But the darker gray floor, with the lighter gray seats is stunning. It'd be a lot of work to get a new piece of carpet thrown in there wouldn't it?

Not hard at all. You can get the kits from JC Whitney. The only thing you have to remove are the seats and the sill plates. I think you can tuck it under the console.

Or just hide those with some funky flame mats like me.

You could also recolor your carpet to cover over the stains? Not sure if the tint would match the factory but you could do the whole thing or add a custom border?

Ok, the gray seats and darker grey dash/doors look great on a dark carpet. Makes it seem a lot bigger...

How easy is recoloring it though? If i do a JC whitney thing, am I laying over the previous carpet? Ya know, if i did new carpet, I could do the thing they did on trucks, and stick a foam pontiac dart or something between the feet...

I looked it up and it only has them available for Grand am, Grandprix, and Sunbird. are any of these bonneville compatible?

Try a LeSabre kit. Anything there?

They do have the kits for a LeSabre in about 53 different colors.
