GT3 997, operating hours and average speed

Hello to the community, with me burns??. I have a vehicle on offer, where I grüble something about the data. I almost already agreed. Are the data plausible from your point of view? Vehicle driven sporty, also on tracks for trackdays etc. But no race track operation. Hobby drivers but probably already a bit ambitious. Mileage 40.000 km Operating hour counter 472h (that should be the airbag, right?) Operating hours at overspeed 1 382h, operating hours at over Speed 2 382h Operating hours at overspeed 3 0h Range 1 83 Ignition (Piwi) Range 2 15 Ignition (Piwi) How do you see that? The car has been moved very quickly, right? That’s what worries me. If the data are as I think it would be an average of 84km/h over all operating hours. With operating hours 1 even 105km/h. That’s really a lot! I would be happy about your help, because I’m not far from buying. Greetings Gordan
