2004 Mercedes-Benz E-Class E500 Rwd 4dr Sedan (5.0L 8cyl 7A)
What a nightmare! It's just so much fun to drive a 6 year old Mercedes with only 52,000 miles that doesn't have an operational radio. There is a widely known issue with the radio with these vehicle (go ahead and Google 2004 e500 radio problems) yet no one at MB cares! The dealers won't go to battle for you even though they acknowledge it's a widely known issue. MB Customer Care? Well aren't they the most pompous and arrogant individuals on the planet. Go buy something else, there are far better luxury automobiles out there.
At this point, ZERO!
Take care of your owners and stand by your product! Sure I know you offer a 4 year 50K warranty. But why does the radio break on a vehicle with only 52,000 miles that is only 6 years old? They want me to buy a radio for $800 yet they aren't even sure if that will solve the problem!
