Mercedes Forum - Mercedes Benz Enthusiast Forums - Purchase advise on 2010/2011 E550

Hello everybody, I am new here and am looking to get back into a benz. My last benz was a 2000 E430 and since then I've had nothing but cadillacs. I am looking at the E550 as I wanna get back into a luxury performance sedan and this seems to hit all the points I'm looking for. I was also looking at 2012-2014 CLS 550 but these seem to be more pricy than the Es and the one I went to go look at in my price range had side-swipe damage that was poorly fixed.

Anyways, the 2 I am looking at now is a 2010 E550 sport 4matic with 60k miles, beautiful white w/ black mercedes sport wheels. This one is closest to me and I really like the look of it. Went to test drive it today all electronics work, only thing I noticed was the rotors may need to replaced because they shake when stopping and there seemed to be a sound similar to hub bearings. I told the salesmen and he didn't deny me but said that the previous customers who test rode didn't mention it. I will be calling the dealership who did the service as this dealership is a mitsibushi dealer. Regular service records on the car with carfax, they also had the starer replaced.

The second one is a 2012 E550 4matic with 63k miles, beautiful black w/ standard mercedes star AMG wheels. The 2012 has the 4.6tt v8 I plan to test drive it at the end of the week.

I will be performing a majority of the work myself as I have with all of my cars, motorcycles, and jet skis. From the research I've done these seem to be bullet proof engines and transmissions. The car will also be a daily driver.

Thoughts on these? Things to look for/avoid, common problems I may have looked over?

Thanks so much!
