Just had mine done. NEW front Arnott struts @$700 each (included faster shipping) plus 6.5 hours labor book rate at my indy(@$80/hr) so it was $1920 plus tax.

They were able to do it in about four hours because they are fast but they charged me the book rate because they did the sensor diagnosis and re-positioning (sensor was installed wrong which BMW could not figure out as well as the indy for the PO) for no charge and they messed with other things I wanted evaluated. SO FAR IT IS FIXED and working perfectly.
