Assuming your machine runs as it should, I think your still getting unnecessarily beat up on this deal. When you go to trade (assuming you do), and the history of the machine is ran. It will show all the work done to it, inside the first year. That is a resale hit in value that your unnecessarily taking. If you plan on running the wheels off of it maybe then it doesn't matter so much. You don't indicate they gave you any input on the repair, unless you haven't shared that. I think that should have been a new engine, not rebuilt. I realize they gave you a loaner, but they, in my view, are obligated to. I would at a min. make sure that you get a new engine warranty from the date it goes back into service, if not additional full machine warranty. I believe CAT is two years on the engine, but you probably know what that is for sure. Things happen, but I think CAT is obligated to make you whole on such a new machine. Rebuilding a burned down engine with a rebuilt one inside the first year of purchase, doesn't accomplish that at least to me. However as long as your happy, that is what matters.
