Guys,
Can you recommend good enthusiast MB mechanic shop in Northern Virginia or DC area? The one that does not charge crazy money for oil change.

I found few, but do not know if they good

I do not want to go to the dealer, cause they charge too much for simple oil change and I am not sure what they put in. Small shops gladly take your oil and filter and allow you to watch they work too.

I cant knock curry,,,great guys and my experiences have all been first rate. I reccomend them to anybody that solicits my advice...provided they don't drive a Benz.

In that case it's Benz Elite all the way! These guys have been honest, fair and knowledgeable. Their rates are competitive and they really care about their customers.
They are the only ones who have worked on my car and have completed some tricky installs. They don't stop until it's perfect.

Good luck!

someone noted not long ago that fairfax service center had fair pricing and was very decent.

i've been going to mars (http://www.marsautogroup.com/). pricing is similar to that of benz elite.
