The e500 has many issues espically the 2003-2004.
My 2003 e500 has had
3 airmatic suspension struts replaced
Drivers side door loack actuator replaced
Third Brake light repleced
2 batteries replaced
Battery Control Module replaced
Change over heat control valve Replaced
All at my own cost. keep in mind Airmatic Suspension $1200-$2000 to fix per strut. Make sure you have a deep pocket for repairs as any third party warrenty company will gladly accept your money for a warrenty but make every excuse under the sun as to why they cannot cover an issue. Buyer beware
