I hate to rain on the 04 GT 2 parade. But I took delivery of mine Thursday and returned it Friday. The car was a slug.
So you did at least 3000 mls in one day? Wow.
Let me explain a little bit: the motronic on the GT2 learns. It not only learns, it also tries to protect the engine. For the first couple of thousand of mls, the GT2 engine, drivetrain, gearbox, etc. need to run in to be able to create maximum performance figures. Of course the GT2 has impressive performance numbers from the beginning but not from 20 mls. You need minimum 500 mls to get a decent performance and even more to reach the performance max. Another thing: if you drive the GT2 hard from the start, it can happen that some parts of the engine or drivetrain don't work as they should. The GT2 engine is not a mass production engine and it needs proper brake-in. I know some people in the US believe that myth that a hard brake-in is the best but this isn't true. The first Porsche which actually doesn't need a real brake-in is the Cayenne. In Germany, we have no real brake-in rules (max. rpm, certain mileage). But ONLY for the Cayenne. Surprisingly, the Cayenne for the US seems still to have tight brake-in rules. And of course it can't be excluded that you just got a bad car.
But selling the car after one day is a bit...extreme, if you ask me.
