We just bought a car for my daughter, at one point we looked at a Nissan Maxima, 95,000 miles on it, loaded with options, and priced about 4k below book. The dealer had just gotten in and didn't have a chance to detail it. The car was completely trashed in side, and the body had a lot of scratches and dings. The dealer said it smoked a "little bit". I watched him cold start it, and he was covering the seats so we wouldn't get dirty riding in it. I told him don't bother I wasn't intersted. I was hoping to get a car that was just a little dirty cheap, but I think the car had been seriously abused in terms of maintance. I think the rings, valves etc were shot on the car. I always wondered what the air cleaner on that car looked like.
