I had this done last Thursday at Bellevue BMW, took 3.5 hours...
My car is running smoother with better throttle response. I am at 137 000 Km
BMW Bellevue has bad reviews on Yelp and google, but I received top-notch service. The price as stated is $369.00 + tax. it seems to be the regular price.
If anyone is looking for Hankook Tires while in Seattle I know a guy, who loves Canadians.
