For the most part its pretty expensive which is why I try to buy a new one with the 4 year 50k mile warranty. Take for instance an oil change. Here at the Portland Oregon deasler you are looking at a couple of hundred dollars for a basic oil change and some minor check outs. But, if you have a reliable vehicle you should be ok. I have also heard a lot about oil leaks from the main shaft where the engine is replaced. I am sure that can be expensive too if not under warranty
