When you buy from a dealership, pretty much ALL vehicles come with some sort of warranty. Even the shadiest of used car dealerships are required to give you at least 30-90 days, unless the car is specifically sold 'ASIS'. I believe the factory warranty on my '99 was 5 years or 60k miles, so it's POSSIBLE that it could still be in effect if the mileage is low, but you should have something in writing from the dealership stating exactly what your warranty period is and what it covers. If you purchased the vehicle about a month ago, chances are very good it's still covered under the dealership's warranty, even if the factory warranty is expired.
