Up near Marlborough but that's a nice run down through Salisbury on a roads :-)
Dave, give Laurence a ring at Autolusso, you'll find contact details on his website, he does a free saturday surgery if you book it up, that gets your car a quick look over plus you get to find the place and meet Laurence, oh and you get to see a few Alfas at the same time ;0)
This forum is full of great advice through searchable archives or through running threads and full of people who have been there and done it with most of the problems you're likely to come across.
If you get a problem my advice is not to panic, well not straight away as many issues can be quickly rectified, Alfas are characters, not merely motor cars and each one is an individual, you and Autolusso will soon get to know your individual.
As its a new purchase it might be worth trying a thread here or the General Alfa forum just to see if it has been owned or at least known by someone here, history with Alfas is well worth having.
For any electrical fault, and they are well known for it, first check is always the battery, Im mentioning this because its a new purchase and winters on the way, a slightly iffy battery will cause no end of problems.
Getting to know the reboot sequence is another good idea, its in the handbook or on here, just a case of disconnecting the battery for 20 minutes and doing the resets.
I think I crapped myself when I first started reading this forum and I bet many others did as well but as someone has already said, most come to forums to discuss problems so all forums are full of it.
Good luck with yours, hopefully you have got yourself a good one, now enjoy it.
