Hello All - my new to me 2001 SLK 320 is my first MB. I bought it 1 year ago from my father who got tired of hoisting himself out of it at age 76. He was the little old man who only drove it to the lost office on Saturdays. Only 73k miles when I got it. I already appreciate all the great information folks have posted. Installed an aftermarket stereo and resolved a check engine light by cleaning the Mass Air Flow sensor. Thanks for having me!
