Leasing or bank loan for new polo?

Hello, I plan to buy a new VW Polo in the course of the year, should I lease the car for 4 years and then finance the remaining value for 3-4 years or should I take a bank loan directly and buy the car bar and then pay off directly 5-8 years at the bank? The interest of the VW Bank is of course lower, but for that the dare still belongs to VW and not to me, so I could decide myself where to have it repaired and similar. can continue to help?
