Car now has 10,000 miles. Has been at the shop 5 times. 3 check engine lights. I get same brake problem that everyone else has a problem with. Engine knocks and was told this is my problem due to California does not sell 93 octane gas. Rough starting in the morning. I have contact the dealer manager he tells me don't bother until the car has 12,000 miles. Mercedes direct says you have to get these issues resolved with the dealer. Has spent a total of 28 days at the dealer. Buy a M5.
I love driving this car! It feels faster than the Porsche Carrera S Cabriolet I traded in, it's infinitely more comfortable and it's capable of swallowing massive amounts of miles in a day. Take a road trip in one and you'll never want to fly (in the air) again.
Very nice car. I had a E55 prior to this car and it was also very nice. I did like the twin turbo in my e55 but I like the seven speed transmission quite a bit better than my old car. Plenty of power but gas mileage is terrible. All in all a great car.
I was in the market for a sporty sedan and I had mixed emotions about the M5 vs. E63 and I am positive I made the right decision on picking the E63. The overall performance of the newly redesigned AMG motor really presses you up against your seat. When have 507hp under the hood with 465ft-lbs of torque trusting you past the guy next to you its fun to see their face when they catch up at the next red light.
