2005 Mercury Mountaineer Reviews

For no reason my 2005 mountaineer started spraying oil everytime I stop gas...just got an oil change two weeks ago
Very reliable and nice to look at. Comfortable and quiet. The only problem I had with it was one of the back windows stopped going down. Quickly repaired by the dealer. Hasn't had a problem yet I've had it for a year and a half. I recommend it to anyone. Just if ur going to buy it used completely check and test it out before signing anything.
