I brought over my 2009 159 2.4 jTDM (210) TI 3/4 years ago, and I wouldn't' do it any other way. The best spec 159 at the time here was €15k on carzone, and wasn't TI.
I went to LoveAlfa in Birmingham, and found them great; they held the car for me and had a selection of similar ones I could buy (I test drove the TI looking for a reason not to buy it). Guy told me that the Sportwagon boot opening is actually smaller
than the saloon, so check this side by side, I did a quick visual inspection, and I'd say he was right.
There were some cracking Spiders and Breras that nearly stole me away, but I kept it sensible in the end.
This one is a 2.0 TI http://www.lovealfa.co.uk/vehicle/al...saloon-122012/
Buy a cheap return flight, no bags, mine was about €45. You need to be prepared to walk away, not having a return flight makes that hard!
Book the ferry only after you've paid for the car, I did it online (Lovealfa lent me a computer).
I left the time very tight, and ended up pelting through Wales at.. 70mph, honest your honour. Leave more time than I did.
In my case, my AIB debit card couldn't be used to buy the car, as the £6495 price tag was too high for my card limit, check this before you go! In the end, I bought it with my credit card, after transferring money into it from current account.
VRT was €2,500, reg plates around €20. First service, including nearly due timing belt job, at TI Autos, was €2,200. Still saved a packet over the Irish car.
If doing it again, I'd probably make the trip over to Veloces in London, they have a massive selection, if the one you go over for doesn't do it for you, there are 30 more that might.
Edit: Had a quick look there, Veloces seem to have loads of Guilettas at the mo, but few 159s. LoveAlfa have quite a few 159s of both flavours.
