First time NL for myself and employer

My wife and I are looking at the Zeekr 7XP to novate and take advantage of the situation prior to the incoming changes. At this rate we will have a newer car than our current palisade, paying less per month and then the savings on fuel.

As a first timer, is there something I should be looking at doing/not doing to make things easier or avoiding? I guess generally just anything you wish you knew prior to your first NL, that you pass on to newbies like myself?

Any particular NL companies to steer clear of?

Apologies if this sounds like such an open question, just trying to make things as easy as possible for ourselves and my employer.
