While I appreciate the humour, would it not be an option to just purchase the custom-designed spring-assist strut that BMW install in this vehicle in other markets? (As Weasel suggests, and which other owners seem to have done?) I am sure if BMW NA was able to charge world prices for this vehicle in North America, they would be more likely to fully equip the vehicle with features such as this that they have already designed and sourced. Since they can't, you get a decontented version. You may even have the spring bracket already, from reading the posts above.

Item 5 is a gas pressurized spring, part number 51476980060, $57.09
Item 6 is a spring bracket, part number 51479138212, $10.17
