I bought a SL600 and had the local dealer repair the "check engine" light. The dealer diagnosed the problem as a intake gasket repair and charged me $2700. After driving 25 miles the light came back on. Did the dealer squeeze me for over $2700. The car has 54000 miles and was one owner. I hate to think that the dealer screwed my for extra work that I did not need. A SL owner said that it might of just been a faulty o2 sensor.
