Yeah I wouldn't be surprised. Even without the EV-factor, German cars don't have a particularly great track record for depreciation. It's a marvel to see just how much a VW GTI, for example, can depreciate in year 1.

Sucks if you buy a GTI, but the depreciation is actually kind of positve for German private buyers of "business-compatible" cars. Over 50% of VW cars in Germany have businesses as first owners, mostly due to business car taxation rules, so they enter the private market as used cars. Given how long cars last these days (yes, even VW - mine is from I think 2009), buying used is a no-brainer if money is at all an issue.
