Yeah it's very early days. I did love the DS3 but I'm very excited to have the DS4, early impressions are very positive. Went for the 115 because of economy, but even so it feels more than powerful for me especially as it will spend most of its time in traffic jams commuting to/from work.
I think the DS4, like the DS3, looks great in white but there seem to be more whites than any other colour, all the DS4's I've seen in the past few months have been white except one in black. Hence I decided to be a little different, must say I don't regret it - I really like this shade of red (Babylon Red).
