Just purchased a 1991 300sl, 104,000 miles. No problems to report, however, been reading about electrical wiring harness problems affecting certain model years from 1992-1996. Some report problems with the 1991 model years to 1996. does anyone know exactly what model years, and/or model cars/engines were affected? trying to figure out if I need to start a more detailed search under the hood. Can anyone offer any input?
