Yes.We bought Grandma's 06" Lucerne with the 3800. Great car and will probably last another decade. I worked at a Buick dealer from 77-90 and witnessed many 3800's with well over 250,000 rounds and very few intake issues.
in fairness, it wasn't till 95 they started putting plastic intakes on 3800 engines. They were metal till then.
As that first article i posted pointed out..were some initial “ teething” issues. But they got solved pretty quickly.
