Recently my beloved classic 95 SL500 was having an stuttering issue. After being quoted pricing of $500-$2000 by another "german specialty shop" to replace everything starting from spark plugs, wires and fuel injectors....a friend recommended Patrick at MB Automotive Services here in Rockville.Went in and explained the situation with my SL to Patrick. After explaining to me that the other diagnosis could or eventually be necessary....Patrick informed me that he would like to start at the fuel filter as the cause of the problem.Needless to say, ended up saving a TON of money! These guys know there stuff! They are TRUE GERMAN CAR SPECIALIST!
