I dont have a new Kluger but my 2008 still looks new.. Number 1 step as most say keep it in a garage especially at night to avoid getting dew on the paintwork than drying out during the day with dirt in it. I wash mine every week, not sure about twice a year, musn,t have dust where you are and make sure you chamois off, wash in shady area not full sun. I use Meguires products so Meguires car shampoo. Polish once a year with Meguires Deep Crystal Polish than use Meguires Canubra wax,, I rewax after 6 months, the polish does not remove paint and the wax protects the polished paintwork and makes it easier to wash and keep marks off. I also polish and wax the rims. Inside on leather use Meguires leather conditioner. If you use Armour All or similar product on your dash make sure you DONT get on perspex that covers your speedo gauges etc, it will stuff it up eventually. Anyway that my tips and they seem to work for me.
