im looking for some decent seat covers for my 2011 mustang cause i can see my leather starting to turn black from my cloths. Any recommendations? thanks

Looking for slip on's

 

Decent and slip on don't go together, IMO, so I'd just go to your local Pep Boys or other handy store and get whatever floats your boat.

 

I have always put Wet Okole seat covers in my vehicles.

 

get a meguiars leather cleaner and conditioner kit and enjoy the seats as they are.

 

You can always go the sheep skin route. This is what airline pilots use. They are warm in the winter and cool in the summer. I used them for years, before heated seats. Any car magazine will have ads, or if you live in a large metro area, there should be stores specializing in them.
