Every manufacturer turns out a few models over the years that have a special look, they just stand out because they're visually appealing from every angle, maybe the designer took a little extra time to make all of the lines flow, he kept at it until the proportions were right and didn't sign off on it until he was satisfied. The Moto Guzzi 1100 Sport is one of those bikes.
This particular example is a European model with the speedometer in kilometers per hour. The paint and overall condition are very nice and the previous owner was the Wisconsin Motorcycle Museum. Mileage is only 7200 (11552 Kilometers), which, for a 1997 motorcycle, is quite low.
According to the seller there are no mechanical problems, the exhaust system has no dents or leaks, original tool kit is intact, paint has normal chips from road use and judging from the photos, there's nothing to indicate the bike is not in excellent condition.
As someone who currently owns a Moto Guzzi, I can vouch for the great sound these Italian V-Twins make and, as noted above, this model is one of the best looking of the entire Moto Guzzi line. If you've ever considered a Guzzi, this would be a great way to try one out, in fact, it may be a keeper. It's for sale on eBay.
