If it turns out that way then ok, but it could very well turn out to be a problem with the engine itself, Im going to guess nothing to do with previous owner, just was bad from the factory and just finally had it and broke or is making noise.I have put 10k on it since I bought it, and havnt had any issues since then. I do notice alot of electrical problems with the computer but I dont think any abuse could cause that, I could be wrong though.
