I was schocked to see all the other positive reviews. This car is a ticking time bomb and GM knows it but won't do anything about it. It should have been recalled. They used a plastic plenum part in the intake manifold cover that melts. No getting around it! Possible problems include coolant leaking, head gaskets blown etc, all very labor expensive repairs that will cost in the $800 dollar range. I bought this car used at 48,000 and spent 600 dollars on that repair. Two years later at 75000 spent 800 on a head gasket. Don't buy this car unless you want to keep pouring money through the hole that will develop in the plastic part that GM won't issue a recall on.
It's a done deal. Gm already corrected this on it's updated 2000 Lesabre Model. However, nobody, I repeat nobody should buy a LeSabre from the model years 1997-1999 unless they want to keep pouring money into fixing GM's error by using a plastic part that melts instead of metal!
