...for the past two years I have used Just BMW exclusively for all of my 10-year-old-5-series' maintanance and repair. Everytime I need service, I am impressed with quality of work and the professionals that work there. I have used BMW of Dayton, Jake Sweeney BMW, and the BMW store before I found these guys, and the difference is night and day. The mechanics at Just BMW know what they are doing, and seem to enjoy doing it. Also, I've never been pressured into additional or optional repairs at Just BMW. I've seen jaguars and merc's in the mechanic's bay so I know they work on other stuff.
...give 'em a call and see the difference.
