Second poster here. Read the posts here about the head gaskets on the Northstar motor. This motor warps when overheated. Posters also say that the motor has to be pulled and replaced. Do your homework, google it. Don't discourage my comment because of the fact that he got a steal for it.

If the head gasket has already been replaced recently, the new owner shouldn't plan on replacing it for a long time as the first one probably lasted for over 100,000 miles. Why do people come on this site and try to scare people and make them think they just bought a lemon?? I have owned 3 GM cars and they have all been great cars 2 of them had well over 100,000 miles when I traded them. FYI 1 was a Chevy and 2 were Buicks.

I have owned 6 Cadillacs with the Northstar engine. (all of them are different BTW) and only the Eldo needed its gaskets done, and it was a 7 hour job that I did in one weekend not too bad. No need to pull anything.

I recently bought a 1999 Cadillac Seville SLS with 73,000 miles. First let me say I have only had this car for 4 months, but what a great 4 months. I bought the Seville as a second car, and boy do I love it. No problems and it's an old car.

The A/C maybe a bit loud, but that's it.

I find myself doing things to this car as well. I removed the stereo and the 6 CD player, and added a new radio system with Bluetooth and an iPod connection. I had a light tint put on. I had the car detailed and cleaned.

The Seville is an amazing ride. And man is she fast. I'm so glad I bought this car.

About the windshield wipers not working. I have a 1999 SLS, and really like this car. 105,000 so far, and I've had it for 8 years. While driving in the rain, the wipers stopped working. The lever does nothing. Checked the fuse; that's fine. The owner's manual says there is a circuit breaker that will trip if it's in heavy snow, but will reset when it cools down. This was in rain, and shortly after I started driving. It was not under stress or hot. Never had any trouble with the wipers not functioning completely normal. Now they don't work at all. Anyone have a clue? The dealer will cost a lot, and the local shops won't know what they are looking at.
