Maybe cause they think your stock? The car stock is slow, at least compared to your standards. A slightly modified Ricer mobile could at least be able to somewhat hang with a Stock Turbo S 944. Who knows, maybe they attached a turbocharger to their engines? They are pretty cheap and easy to put in and add loads of power to these things. They most likely also don't know anything about the car. The size of the engine, the power figures, ect. ect.
