2011 S550 NA (naturally aspirated)
I have a mechanic that I trust and he advised me not to buy any type of car with a Turbo engine. So after a long search, I finally found a 2011 MB S550 W221
which is the last year Mercedes Benz S class made NA (naturally aspirated), and in 2012 they started making 4.7 L Turbo engines.
The car I found has 50,000 miles on it and had regular maintenance at an MB official dealer and super clean. My mechanic said the newer S550 class with Turbo engines are guaranteed to have problems but the NA (naturally aspirated) engines have less trouble but they do have many issues.
I have a 2000 E320 with 205,000, miles on it and also a 2002 ML320 with 240,000 miles. I understand that 320 and 500 engines are bulletproof engines. I understand that the e350 engine is not the same as e320 and totally different engine.
So, I like to know if I will be facing lots of headaches if I get this 2011 S550 which I really like the look and also the ride.
I heard about the air shocks that once they go bad, probably around 120,000 miles, it will drain my wallet. But also the Lexus L460 air shocks at the Lexus dealer cost $8900 for all 4 of them.
Any experience or suggestion about the car that I'm going to buy is appreciated.
Buying this at CarMax and they told me about an extended warranty will cost me $4-$5K for another 50K miles or 5 years which I think many forums suggested to buy for peace of mind.
