Just to update; The heart and head battled it out... it was a closely well fought duel... but a winner prevailed. You've probably guest it, yup, I've put a deposit on an Alfa 159, 1.9JTDm, Turimso with parking sensors & that lovely red leather! Also has new front tyres and a cambelt done recently as an added bonus.
I originally wanted a Lusso but most were plus £1000 more, with at least 10k more miles, no cambelt done & illegal tyres. So in that resepect as far as I can tell I've lost the visability pack & some fancy metal trim but potentially saved £1600. So I think I can manage to turn the lights on when its dark, although my last 3 cars have had this and it may take some other motorists to flash me frantically at first before it becomes something I feel I should do again.
Anyway, I'm very pleased. Thank you for all your help and advice.
