it would work
You would set it up like you do when you PCP a car, you put a deposit down of 10-15%, the company insures the marker so you dont do a runner with it, you pay over a 12 month or 6 month period (0%) the marker is straight lined depreciated and at the end of your lease you either like the marker and pay the remainder on it ) straight line depriciation excess (this is the bit where the company makes the money) or you hand it back for another model, or you sell it 3rd party to pay the cost the company has attributed to the marker and you get another one, its a bit like future profing you set up.
Sounds simple, so there must be a reason why company's dont do it. One sec while I phone smart parts and then mail this to myself registered post so nobody steals the idea.
