Don't judge this book by its cover (or location). This is a legitimate German/Foreign Auto repair shop. I found this place by chance, while running an errand in the area. My wife's Mercedes C250 had just fallen out of it's service warranty with the MB dealer, so I was looking for a place to have it serviced that was reasonably priced, high quality, and HONEST! I found it at Benz & Beemer.
Seems like a family owned shop, busy, but not too busy to give personalized attention.
They performed a Mercedes service B on my wife's car for about half of what the dealer charges.
While I was there, had a chance to speak to the owner (I think), he was knowledgable, friendly, and willing to give me some German car buying advice.
