I nearly chopped my e92 330d for the f30 328i SE, was getting a cracking deal or so I thought but the sales donkey had screwed up his figures then insisted it would cost me another £70 per month!
Took the 328i out, 4 doors and non diesel were a requirement, loved the car loved the new interior. It wasn't quite as urgent as my 330 but all around I preferred it.
Get a test drive if you can, the trip computer showed 17mpg tho on my spirited drive through Scottish twisties however on the motorway that jumped to 45mpg.
I reckon now that I don't do the miles that a petrol will be ok for me.
I know what you mean re the "itch" since the above I've explored a few options finding it hard to get away from bmw though for overall quality and drive plus they are doing favourable finance terms at present.
Btw anyone I know who gets a "normal" Audi has got a bit bored quite quickly.
