I have a 1991 560 sel , in VA. it cost me $700 , I tried to do it myself but it was to much trouble , make sure all dash light work after they finish , they unseated 1 of my blubs and had to go back in to fix it , had to take it back a second time because it wouldn't start , sounded like it wasn't getting gas or fire ended up being the switch , to much trouble for a home merchanic .
