Fairly new member. Wanted to share some photos of my 2000 LeSabre Limited with 132k miles. It has a couple of issues but I think it will be a good car.

Welcome the forum. I like the LeSabre, good comfy car.
The 3800 engines are long lasting, but inspect the coolant overflow tank for oil contamination.
The upper & lower intake manifold gaskets along with aluminum elbows area good idea, if they have not been replaced yet.

Trying to get in contact with the original owner. He had the car from 2000 to early 2018. He had a lot of things jotted down in the back of the owners manual. The elbows look to be the original plastic ones so I am preparing for the worst.

Nice car, looks pretty good for its age. Agree on everything Soft Ride said. Good thing you have some history on it, that'* always a bonus.
