@InvestmentPapa well there is a roof box in the garage that I use myself 1- 2 times a year. The rest of the time I provide the change for a small fee. In the past I have always taken the money to finance with the appropriate holders for the changing business cars. Now the money may in the ETf what comes from there... roof box cheap on eBay classifieds bought (Thule 60€) then carrier in addition bought 200€... In the meantime, certainly 10 times rented out for about 80€ each.
