2011 E550 vs 2012 E350
2012 E350 4matic, black on black, 25k miles, final price 39,900 with unlimited mileage warranty out to 4-1-2017. Really nice car, mint, during the drive it felt a little soft but super smooth. Sticker was 59k
2011 E550 4matic, 40k miles, diamond white with dark brown interior, final price 41,000 with unlimited mileage warranty out to 11-1-2017. Really stunning car, lots of options and that amazing v8. Sticker was 70k.
I'm leaning towards the E550 but would love input on the following:
1. With 90% highway driving can I expect roughly 23-24mpg in the E550 and 27-28 mpg with the E350?
2. Will the extended warranty cover the airmatic suspension bits on the E550? I hear they can be problematic with age...
BAsically I'm planning on driving either one for at least 150-200k miles and am curious if one will be more reliable and or cheaper to maintain than the other. Thanks in advance for the feedback!
As far as 150-200k reliability is concerned, the only real difference would be the airmatic which historically are not known to be very reliable once you get some mileage on the car. It's also an expensive system to replace.
Personally if I wanted to put that many miles on a car outside of warranty I would not be looking at ANY Benz.
Good luck!

do you need 4 matic? if not you should look at a bluetec. You should def look at a distronic car if you drive so much like me. Its a god send on a daily commute.
the BT will give 33mpg avg. The E550 will give 21 and the 2012 E350W4 will give 26. I averaged 23 mpg in the 2010 E350w4 I have.
in 150k miles, fuel will cost 16300 for BT, 25000 for E550, 20,000 for E350W4.
The BT will have a higher resale at that mileage too. Not much but 1-2k higher than gas.
The BT sux from 0-30 mph but rocks from 30-100 mph. The E550 is awesome at all speeds. The E350 is fine as well. If I drove in the neighborhood a lot vs highway I would not suggest the BT. Its like driving a train.. has to get going but once in motion, it loves to keep going.
The unlimited CPO warranty is great right now.
I love the BT, but I suggest at least drive a distronic car for 10 min on the highway before you settle one one for next 4 years. The other advantage of BT is 650 mile range so fill ups once per week vs every 3-4 days. I am quite happy to see 35-37 mpg in the dash when previously I was used to 19 mpg in V8 cars I have had previously.
Airmatic is covered in CPO, as is bushings.. which is great because BMW CPO does not cover that, and they will surely die in 150k miles.

Your MPG numbers are spot on. I had a 2011 E350 and now drive 2010 E550 and those are what I got (get) as MPG. Now mine are not 4Matic though.
To my knowledge the Airmatic is covered under the extended warranty.
Go with the bigger engine. You will love it!
Re: Airmatic, I had over 70K miles on my 2004 E500 with only one problem - a leaking air spring (replaced under warranty) when the car was about a year old. At about 10K miles and a year and a half, both rear air springs on my 2011 E550 were replaced under warranty due to leaks. I'm a little under 20K miles now and haven't had any more problems with the Airmatic suspension.

I've had 3 E350's - a 2006, my wife's E350 with Distonic and my 2010 White E350 Sport -
Spot on with the Distonic - great to have especially for long distance and daily commuting.
I traded in my 2010 E350 for a CPO 2012 CLS550 in June and I love the V8 - On a recent trip to LA and back to San Diego in the diamond lane and at an average speed of 80 I got almost 29 MPG!!! Not bad for a V8 with tons of torque and power.
Good luck in your choice

This was last week.
Hoping summer will be better.
True pump mpg is 5% less on avg.
Running 17 inch runflats at 40 psi right now till I get new wheels.
By the way, tell any of your friends that if they want a certified Mercedes this current offer is just insane. I was able to get warranty coverage with UNLIMITED MILEAGE out to 11-2017, they are picking up my first 2 payments, my first 2 maintenance visits (including the spark plugs at 60k) and I got 1.74% financing for 66 months.
I never thought I could afford an E550 Benz but given this offer any my current situation, I simply couldn't afford to not go for it!
Thanks again from a very happy new Mercedes owner!!!
