Hi and welcome.
I do love the Sp1's very nice!! S4r is basically a naked 996 so the usual Ducati stuff to look out for im sure someone else will be along to direct you to a thread or try a search. The S4r has only been out a few years so has all the later electrics etc.
At 12,000 miles or 2 years the major service should be carried out which includes a belt change I would ask if this has been done as it can be around 550-600. Also ask if the rockers have been checked to as part of the service.
I'll have a pint of Guinness seeing your at the bar
Just noticed your in bristol to, which dealer is this at? its quite cheap for an 03' S4r
