回复：又查了一下，确实是E350好，但是坐得高惯了，不习惯坐sedan了。

E350 has 2 wheel drive (rear wheel) and all wheel drive (4MATIC), whichever you choose.
It has gas version and diesel version - E350 has a gas engine, "E350 bluetec" is with diesel engine.
Don't know what OTD price is, but you can find it here  www.edmunds.com/mercedes-benz/e-class/2013/features-specs.html
