Is plastic plenum a deal-breeaker for 1999 Buick LeSabre 3.8 V6 Series II?
#9
The overall motor is durable, but the plastic plenum used from '95-on might not be. I'd be more concerned about the rest of those cars, not the venerable (albeit largely redesigned) 3.8 V6.

It's one thing to be doing your homework concerning known-faults of older cars, but don't anybody get wrapped up in it, if what it amounts to is a one-time repair of a few hundred bucks, particularly if the fix is known to be stronger than the original (and therefore not likely to be an issue again.)

Just ask a mechanic familiar with the situation what it would take to fix it --- should it ever need it --- and use that to judge how much of a problem that is.
