1st of all 80% of the time I'm not trying impress anyone and alone, so I cover seats - look up an "Aires seat defender" on AMZN..
it's not a seat cover, just a rubberized black sheet that protects and looks good - the leather stays new..take it off/on in 5 secs when you have guests....
as far as interior protectant - your leather is coated with a plasticizer so it's not really leather to take care of iut...two good ones for the whole interior are aerospace 303 and Poorboys natural look..google them and read here :

your lexol is fine if you own it...but the poorboys makes it clean with no shine - my fav....
