I'm on the fence as whether or not to go ahead and buy one. this would be my 5th mb. previous 190e ml320 e430 and e500. i have had good luck for the most part, i was subject to the key disaster associated with the ml's, but all in all its been ok. just looking for some positive feedback on the sl. (it would look so much better in my driveway than the clk430). lol. im just really concerned about getting killed on repairs. Thanks
