At noon, the guy's car arrives back at the dealership on a flatbed truck, dripping a big puddle of oil out of the bottom of the engine. The guy is ranting about the quality of the motor and how it "just broke".

We put it on a lift and the oil pan had several outward-facing rod dents in it and a front-to-back split in the pan that was leaking oil.

Well, even back then, Porsches had a rudimentary ECU that retained the highest rev's. The techs got the revs out of the ECU and discovered the engine had been revved to 10,200 RPM - this on a car with a 7000 RPM redline and no rev limiter.

Confronted with that evidence, the guy confessed that not more than a mile from the dealership, he pulled alongside a guy in a 911, took off to drag race him and missed his 2-3 shift completely - revving the engine to the destruction point.

Car abuse isn't only the domain of stupid dealership people.
