Define "abuse." I drove the wheels off of my old 300D until I sold it at 348k miles. It still ran great and started fine in single digit temps. The moron to whom I sold it didn't get it when I explained that it was an old car and needed the oil checked and refilled regularly. Two months later it wouldn't start in freezing temps and "that gauge that goes from zero to three" was broken as the needle had stopped moving. I drive just as fast in the S420, but doing so rarely requires the engine to rev above 2500 rpm, which seems a waste. As long as the injectors, IP and valve timing, etc are in spec, go use all 77hp.
