Be a little careful with some of your analysis. For example, you mention a Mercedes e320. There is no such thing anymore. So the last year or a previous generation vehicle is certain to depreciate more steeply than the first year of a new generation.

E320 is just an E-Class

The 320 just designates engine size. i.e. 3.2L V6

The new 350s, are still the E class, just with a 3.5 V6

I'm a Mercedes owner (CLS) and enthusiast. First, even if the distinction was only the engine displacement, the bigger engine is certainly more attractive to buyers.

But it's not. There was a redesign between those model years. Mercedes rarely updates engines mid-cycle. In this case, it was a dramatic redesign, an entirely new platform. The new E Class -- E350 or E550 -- is a very different car than the E320.

ah yes, didn't catch what you were saying in the original post...then yes, the redesigns should be accounted...but since they are only looking at E320s, the redesign hit should affect all years.

But it LOOKS like the right-most (highest) data-point must be the new car price? And it shows that steep drop off going to 2009.

And in the case of the E-Class, 2009 was the last year of the old generation (W211 IIRC). So yes, if you graph E-Class prices right now, there will be a huge drop there.

If the 2010 Data Point is something he's purporting to be a "2010 E320" then it must not be a US model. In the US MY2010 began the W212 E-Class.

I applaud this guy for putting together so much data. I just wanted to raise this question because the way the data is presented confuses me a bit.
