Great car! Comfortable, nice interior space, classy materials, and the wagon’s loading capacity is a major asset.
Combo AC/DC charging socket — in other words, Home/Highway — all-electric range over 100 km.
IT HAS EVERYTHING TO PLEASE!!! AND ABOVE ALL THE PRICE!!!

For the current price (€36,000) the car is an absolute steal!
Unfortunately cars with different equipment levels are being compared here, which is absolutely not acceptable!
The Seal6 comes with every possible extra, for which on the Passat you'd easily have to pay an additional €12,000.

A smart estate, plenty of space for everyday use and extremely economical if you can charge at home now and then. The electronic assist systems are pretty annoying, but can be deactivated before setting off. It needs some software adjustments.
