I bought this setup from a member here in June 2011... I literally have not installed the rack. It seems the screws didn't fit into the mounting points on the car properly .. it may have been operator error or you may need new screws to secure the towers to the car. Other than that it is in excellent shape. I don't have the e90 any more and I don't think it would fit our f30... and I have a pickup truck to haul the bikes so I no longer have a use for it (everyone always likes to know why people are selling, so there ya go!).
I purchased it for $650(shipped) and I'd like to get $500+ shipping and if shipping gets pricey we can negotiate that part.
thanks!
Matt
