As [MENTION=3203]Rogue[/MENTION] said, whichever one(s) you look at and consequently consider buying, make sure it has had the belts done already. It's an expensive job, as you may already know, so if it has already been done, then it's one less thing to worry about.
72k 5/6 years depending on the registration date. I'd say 5 to be safe though. As said, the newest 197 will be about 5 now so look for one with a belt change already done.
