Yep the plate was an aftermarket thing, cos mine doesn't have it. In the engine bay there will be a plate saying ***/1000 (*** being the build number obv).
If its pretty much standard then chances are its not been ragged too much. I found when I was looking for one a lot of the ones with engine rebuilds had fancy turbos, exhausts uprated this that and the next thing. Also got a pretty low mileage. Same as mine had actually so the guys that have had it have prob just used it as a weekend toy. If its got a full service history and lots of receipts then I'd def go and have a look at it.
Hope that helps
