I forgot to mention complete service records and all keys a must. Especially the Red key.
On any used Ducati check for tank swelling. Look where the tank rests against the frame at the rubber bumpers. Ducati replaced tanks for years but that ended on January 1, 2014. Thing is they replaced the same tank so no gain down the road. It was a free tank however.
It was the type of plastic used and since the EPA only allows certain manufacturing chemicals in the US there was no fix. Attracts water. You will notice most new models now have metal tanks. Must of cost Ducati a fortune.
If you are going to use the bike for commuting back and forth to work and out of town trips you might look at the Multi Strada. (many roads) Wonderful motorcycles but get the 996 motor and not the 916. Not everyone's "cup of tea" but highly liked buy owners. ST3s if you want more of a Sport model.
Always go for the "S" model if in your budget. Just my 2 cents.
