You never know when something will break, so why worry. It's a Porsche and is meant to be driven. My 2000 S with a 3.2 liter has just over 75,000 and runs fine. Buy a Porsche with the bigger motor, it will not be under powered a have a lot less stress on the engine do to more torque and horsepower. Simple lesson I learned. My Gravely tractor with 10.5hp engine was under powered and eventually blew up. I installed a 13.5 on it it and it now runs, mows, and pulls with no problem. The difference is nite and day.
