Very nice! And last model year for the Lesabre after 46 years.
Bad luck on motor. These series II 3.8’s are virtually bulletproof with exception of intake plenum. Very rare to find a catastrophic failure unless you run with no oil and even then, they don’t die easy.
Things you’ll have to watch: These cars wheel bearings fail often and brake rotors warp about twice as often.
Electrical system runs around 15v all the time. And the auto headlights are almost always on. As a result you’ll go though headlights fast and even more annoying, the backing lights on the interior buttons blow out.

Congratulation, and love the physical endurance you seem to have to restore that car, and it should be good for another 100K with proper engine/trans maintenance!
