Hey guys less than a month ago I got a new touring 350z.

This is the first new car I have had with leather so I am wondering what if anything I should do to it to protect it.

Is 303 enough or should I put some cleaner/conditioner on first?

 

You definitely want to use a leather cleaner and conditioner recommended by the manufacturer. I'm not sure what Nissan provides with their cars, but you can probably pick up a deced product by Meguiars or one of the other big players in the detailing field.
