Hey lil ant,
well first you would probably have to start a thread to introduce yourself with your ride and make some posts besides WTB threads. After you build up some cred around the forums, maybe more members will be interested.
Now regarding the seat covers, after you get it done on your sedan (i assume from seeing ur threads), post some pics so others can see. I hope it's the type that goes around each piece individually. If it's just a universal cover, that's way too much.
Even if they were high quality though, I dunno if it's worth it. I don't really like the red stitching on anything in my car even though my car is red. For $600-900, one could probably find some 7th gen or cl/tl leather seats to swap out with.
Sorry for being kinda harsh but that's my honest opinion.
