neither is good

First, salvage title car will have hard time to sell in future when you need to sell it. BY the way that car is too high mileage, as a gas engine, its life is at the other end of slope. You will see mounting repair cost down the road.

Secondly, both cars are already changed hands couple times, it's not a good sign. I don't want to go to details on why, but I can only tell you so with my more than 15 years experience of owning mercedes.

Try to buy a mercedes from a wealthy family, the original owner.
