Sal I bought a '99 Seville SLS and it had about 48K on it I think (can't remember now) but I was able to get a warranty out to 100,000 miles. I must say that was definately a deciding factor. I would say weigh out what you want and what you can afford because if you can get an STS at the right price you can buy larger wheels in the aftermarket or from someone who removed theirs for aftermarket rims and still be under the cap.
