That might be tough to figure out since most people own another car so the Boxster never really has a predictable pattern. One guy might drive the car 10K a year but usually on long trips with weeks at a time of the car sitting dry. Another guy might have very low mileage but makes frequent local trips. I'm pretty sure you'd want the car with low miles that was put through the gears with more frequency. Yet conventional wisdom would make the buyer skeptical about buying a low mileage car.
Using total miles to pinponit the highest likelyhood of a IMS failure can be misleading.
The data logger would have to ask the driver some questions about how frequently the car was drive, for example how often gas fill ups were needed. Logic being a guy who only gassed up the car once a month is a red flag.

Maybe its not so much mileage but time. As in the dealer should tell the owner "be sure to put at least 60 minutes on the car every week and no you can't do the whole month's time at at once, that defeats the purpose".

Either way that's definitely a question for the Flat6 Innovations guys.
