The last thing you need is a plane that has a engine with 600 hours over TBO. You are learning to fly and handle emergencies. If you encounter a real emergency with your low time the outcome may not be favorable. 62 is a real concern to me. When you are learning to fly you are abusing the plane more then a casual owner. You will be redline to idle constantly simulating various situations. I wouldn't touch that plane if it was free. Not to mention you have no idea the cost to upkeep one of those. You will be sorry in the end and wish you hadn't.
