I have a DS3 E-Tense on order which I am collecting on 02/03/20.
I was lucky enough to get a proper test drive when my local DS dealer had one for the day. Really good to drive, very comfortable, quiet and refined.
The La Premiere version (which I’m getting) comes with all of the bells and whistles. I can confirm that the seats are manual. There is no electric option available.
I considered the 2008 but preferred the DS3. There’s a wait of about a month, currently, to get a wall charger fitted by Pod Point. This is free as the £359 balance for the 7kw charger (after OLEV grant) is paid by DS.
