Well, don't know quite where to start, but it's great to see your enthusiasm for an Alfetta - I know the feeling. However, rust on these car can be not only unattractive - but downright dangerous. If shock mounts and underbody beams are swiss cheesed with rust, you really need to stay away from it. There is a ton of information on this site, and I suggest to you look into a few threads on restoration of Alfettas, there are several good ones out there showing that even the worst of the worst can be brought back to life - but it ain't gonna be easy or cheap. There's a lot more involved than just getting the car's engine running. Driveline's and the rear transaxle setup can be challenging even to experienced owners. Depending on how long it's been sitting and where, expect to replace everything! Get plenty of photos from every angle and post on this site before purchasing - many of us can point out major issues from the other side of the planet!
I'm not familiar with the "sport" model question, I'll leave that to your countrymen to answer - as we never received anything labeled as such on our shores.
Finally - just because you can afford to buy it - doesn't mean you should buy it! I've invested massive amounts of time and money into these cars over the years, and while I don't regret it - I'll certainly never see a profit should I decide to sell one. Just something to keep in mind...
