Here is another option that I've heard good things about: nextzett 92470515 Cockpit Premium
I might be giving this a try soon, alternatively 3M Leather and Vinyl Restorer.
Used this on one of the girl's Hondas and still have some here. May have misapplied it or left it on too long but it left streaks on the door vinyl that wouldn't go away. It scared me off but, as I said, the problem may only be with me. Just be careful with it and do what the instructor ctions always say - try it on an out of sight location in your car first. But if you read the directions you're already a long way ahead of me.
