Thanks for the input guys. To be honest I was doing 2 hours of commuting a day, the car I had (a beater) was iffy on reliability so I decided to buy new, and yeah it's more expensive but i just go into the dealership and hand over the keys. Having to work on a beater and a weekend car isn't fun IMO.
True the next owner will probably get the worst of it, i never thought of that. Never know i might keep it, who knows.. might as well protect it while i can.
I will probably go the cheaper route with the oil spray since Krown gaurantees it.
