Thank you Marco, Terry, John the whole team at McKenna!
Awesome service and attentiveness.
Installed the Dinan 3.45 Diff. Ordered it literally the last day of the Oct sale. Took 3 weeks for delivery. Called for service appointment for the next day. Brought the car at 7AM, picked it up at 4PM. Loaner was a 2013 328i. Couldn't have been a smoother process.
Now enjoying the new "torque." Have an Eisenmann Race and the drone at highway cruise is gone.
