Where and how best to lease?

Hello, the Grandland X should be! 😉 There is a severe disability of 50 %. At FOH vO there should be “only” 18 %. I heard that 18 are standard, but there are quite FOHs that exist up to 23. Would be the first leasing car. Which leasing models are there? Which monthly leasing rates are to be expected at least? The Grandland should then be driven for 1 – 2 years, then return the one to the FOH, a new … I heard that there is the possibility, e.g. the Grandland officially qu buy asi, pay monthly leasing rates, then let the FOH sell/pay again, order a new one, buy, lease … How does this work in principle with Opel? Where to look for it? Thank you. GLG
