Cheers for all the posts. Wanted to try and reply to everyone who'd posted.
Yusee - sure will do. Not got out properly yet but hoping to see how it handles the twisty stuff soon.
Niall - yes, the fit and finish and feel inside are excellent and the lack of stop-start around town when in hybrid make it very smooth and quiet.
AGB - Ha, might have to consider a name change! Not got HUD as wasn't able to get a car with any additional packages spec'd. The instruments are very clear and well laid out and enjoying the speed limit display in the dash rather than in the main screen on my GTI. It even flashes when you creep over as a reminder, so I'm told...

Fred - makes a lot of sense for me as didn't want to just pick a plug-in for tax reasons alone so think this is a good compromise. Would agree that the 3 Series is certainly a car BMW never really get wrong. The interior is certainly newer than my Golf in terms of tech but it also feels very premium as well. The volume knob is proper aluminium and feels expensive. Not sure about wireless Carplay yet as it seems to just drop off sometimes and can be slow to respond. Plus I don't have wireless charging although being connected doesn't seem to hammer the phone battery.
CookieMonster - Definitely enjoying iDrive, the click wheel is very easy to use and the whole system simple to get to grips with from the off.
Jaceboy - it's got a great driving position, you sit quite low but it feels nice and the seats are good. Not been any distance yet so not sure how that will be but lots of my driving is short trips etc and this is where the 330e makes a lot of sense.
Actually had a sunny day yesterday and the colour and paintwork look great. Going to give it a once over with the rotary when I get chance and get a ceramic sealant on. I did really miss my Indium Grey GTI and parked next to my Tungsten one, I can see why and think grey does suit the 3 very well if perhaps a little boring.
